Ford Super Duty

In 1958, Ford introduced the Super Duty family of V8 engines. Built specifically for trucks, the 401, 477, and 534 cubic-inch gasoline V8s were the largest-block V8 engines ever built by Ford Motor Company (other than the 1100 cu in GAA, developed for the US Army as a tank powerplant; this however was a 'cut-down' V-12, with a 60° V-angle, and was not originally designed as a V-8), and were the largest mass-produced gasoline V8 engines in the world. To showcase the engine launch, the "Big Job" conventional truck variants of the F-Series were re-branded as Super Duty,[2] a name added to other Ford trucks as well. Alongside the Ford C-Series and H-Series cabovers, the N-Series conventional adopted the Super Duty name.[3] Although its poor fuel economy would prove uncompetitive against diesel engines, the durability of the Super Duty would keep it in production into 1981.

In 1987 Ford would revitalize the name as a Class 4 truck badged as "F-Super Duty", Manufactured as a chassis cab with the frame open for a bed that would suit its future application, these trucks would be equipped with the 7.5 liter gasoline engine or a 7.3 liter IDI diesel engine. The weight and class of these trucks would make them the heaviest trucks in the F-Series line at the time.

Following the redesign of the 1997 Ford F-150, the Ford F-Series began a transition in its layout. In response to the changing demographics of pickup truck purchases during the 1980s and 1990s, Ford shifted the design of the F-150 separate from the larger F-250 and F-350 (which remained in production). While still a full-size pickup under the skin, to expand its appeal among consumers, the F-150 adopted carlike aerodynamics and convenience features. To market a truck that appealed towards commercial buyers, fleet buyers, and users who tow, Ford sought to create a separate, dedicated heavy-duty truck platform (in place of using one chassis for all of its trucks). By expanding into two separate but related platforms for F-Series trucks, the inevitable compromises inherent in offering a wide range of load-carrying capacities were avoided. The F-250HD lasted into 1997 (alongside a separate 1997/1998 F-250 based upon the F-150); the F-350 pickup was put on hiatus after 1997.

For the 2005 model year, the Ford Super Duty trucks were given exterior and interior updates. For the exterior, a new grille, front bumper, and headlights were introduced alongside the introduction of a locking tailgate for all pickup trucks. Under the skin (with thicker frame rails), updated Triton gasoline engines were introduced with higher engine output and larger alternators; in response to the increased power, all trucks were given 4-wheel disc brakes (with two-piston calipers). To accommodate the larger brakes, 17-inch wheels became standard, with 18-inch wheels optional (on single rear-wheel trucks); forged Alcoa wheels were an option. The long-running Twin I-Beam front suspension continued on two-wheel drive trucks.

To the interior, several changes were made to improve functionality for end-users. Along with the addition of a driver-side glove compartment, the truck added the option of dashboard-mounted auxiliary switches (for owners who fit equipment such as snowplows, winches, and auxiliary lights); these are switches that were typically user designed. For users that tow, a new option was Ford TowCommand, a Trailer brake controller built into the dashboard, allowing it to integrate with the ABS system and engine computer from the factory.

During its production, the first-generation Ford F-Series Super Duty was sold with two gasoline and two diesel engines.

Replacing the overhead-valve engines used in previous F-Series models, for the Super Duty, Ford transitioned to the Triton overhead-cam engine family (truck versions of the Ford Modular engines).

At its launch, the standard engine in the Super Duty was a Triton V8. Producing 255 hp/350 lb-ft of torque, the SOHC 16-valve V8 was shared with the F-150 and Ford E-Series. During 1999, the engine was retuned to 260 hp. In 2005, the cylinder heads were redesigned to 3-valve design, converting it to a 24-valve V8; output was increased to 300 hp/365 lb-ft of torque.

As a replacement for the long-running 7.5L/460 V8, for the Super Duty, Ford introduced a Triton V10. A SOHC 20-valve engine, the V10 produced 310 hp/425 lb-ft of torque. In 2005, the V10 would also receive 3-valve cylinder heads, increasing its output to 362 hp/457 lb-ft of torque.

Both the V8 and V10 Triton engines are designed with a fail-safe cooling system to protect the engine in case of major coolant loss. If the engine overheats, the engine will operate on half of its cylinders. Alternating back and forth between each set of 4 (or 5) pistons, the set that is not receiving fuel and ignition is operating to pump air through the engine to lower its temperature. Although engine output is limited, dependent on upon vehicle load, outside temperature, and current road conditions, the system is designed to allow the vehicle to travel a short distance to receive service or to reach a repair facility.

Available in both F-250 and F-350 pickup trucks as well as F-450 and F-550 chassis cabs, the F-Series was sold with optional PowerStroke V8 diesel engines produced under its joint venture with Navistar International.

At its launch, the Super Duty F-Series was sold with the 7.3L Power Stroke V8. Initially producing 235 hp/500 lb-ft of torque, the engine was retuned in 2001. Versions equipped with an automatic transmission produced 250 hp while manual-transmission examples produced 275 hp; with either transmission, the engine produced 525 lb-ft of torque. As the 7.3L V8 was no longer able to comply with emissions regulations for diesel engines, it was discontinued midway through the 2003 model year.

As a running change during the 2003 model year, the 6.0L PowerStroke V8 was introduced as the replacement for the previous 7.3L V8 in LHD markets supplied with the American-assembled trucks while RHD ones supplied from Brazil kept the 7.3 until 2005. As before, the engine continued to be produced by Navistar. A 32-valve pushrod engine, the 6.0L V8 featured a single variable-vane turbocharger. While a smaller-displacement engine than its predecessor, its output is higher than the 7.3L, providing 325 hp/560 lb-ft of torque (in 2005, the torque increased to 570 lb-ft). Due to problems with the head bolts Navistar re-designed the engine with reinforced heads, more torque and, power releasing the new design in 2005-6. As with its predecessor, the 6.0L would end its production run due to tighter emissions requirements, replaced as part of the Super Duty redesign for the 2008 model year.

The 6.0L Powerstroke was the target of a class-action lawsuit, alleging the engines were defective. Ford settled the lawsuit with owners and former owners of 6.0L diesel-equipped Super Duty trucks and E-Series vans in 2013, by reimbursing them for the cost of repairs to the EGR system, fuel injectors, and turbocharger, which were common failure points.[6]

Four transmissions were available. Several configurations of ZF5 five speed manual transmissions were offered: Small block pattern, big block pattern, and diesel. Close ratio and wide ratios were available, as well as 4wd and 2wd configurations with the exception of integrated driveshaft brake 2wd versions using the 4x4 style transmission. Earlier s5-42 versions were rated to 570 Nm (420 ft lbs) of torque, while later s5-47 versions were rated to 636 Nm (470 ft lbs). ZF 6-speed manual for diesel engines. An optional 4R100 4-speed automatic was available for either the gas or diesel engines, later being replaced with the TorqShift 5-speed automatic. The 5-speed automatics are rated at exactly 1,000 lb (450 kg), enabling higher towing capacity than trucks with the standard 5/6-speed manual transmission. The 6-speed manual transmission comes with an integrated PTO.

The Torqshift 5-speed 5R110 automatic transmission replaced the 4-speed in the 2003 model year diesel trucks in order to compete with the Allison 1000 series from General Motors; it was paired with the new 6.0 L diesel engine. The TorqShift design in fact has six forward ratios, but only five are advertised, with the 'hidden' gear only used in extreme cold weather. The TorqShift 1st to 5th gear ratios are 3.11, 2.22, 1.55, 1.00, and 0.71:1. It also utilizes an alternate 4th gear, overdrive on 2nd gear of the 3-speed automatic component (0.72 x 1.55), that is 1.10:1 that is used under cold start conditions to aid engine and transmission warm up. On the TorqShift, once the Tow/Haul mode is activated it can help increase a driver's control when towing large loads up and down steep grades and automatically minimizes shifts and maximizes available torque. Upon descent, the Tow/Haul mode utilizes engine braking to help extend brake life and improve driver control. An adaptive shift function monitors the TorqShift's performance over its lifetime, and adjusts shift pressures in real time to assure consistent shift feel and compensate for wear. For ease of maintenance, the TorqShift's oil filter is an easily serviced cartridge design that was usually mounted on the passenger side behind the front bumper. Also the TorqShift's larger fluid lines and a larger transmission oil cooler help to assure cooler operating temperatures, even under the most demanding conditions. This was Ford's first automatic transmission to feature PTO. The transmission can be equipped with an integrated PTO provision (which automatically locks the torque converter providing power to the PTO gear when the operator turns on the PTO switch).[7]

On 4x4 models there is a choice of a manual chain-driven transfer case floor shifter with manual front locking hubs or Electronic-Shift-On-the-Fly (ESOF, a $185 option over the manual) dash knob with vacuum activated automatic and (in case of failure) manual override front hubs. The optional FX4 models are basically a standard 4x4 with an Off Road package that includes a few extras like upgraded heavy duty Rancho shocks, added skid plates for the fuel tank and transfer case, and two "FX4" decals on both back bed-sides instead of the standard "4x4". For all 4x4 models, the 2-speed transfer case 4x4-LOW range has a gear reduction of 2.72:1. Brazilian and Venezuelan versions had only the ESOF transfer case.

For the first-generation Super Duty range, Ford used several different suspension configurations, depending on the model of truck. All models have heavy-duty 3" wide leaf springs and staggered shock absorbers. A standard stabilizer bar is included on dual rear-wheel models and an option on single rear-wheel versions. An optional slide-in camper certification package with heavier-duty springs was available on single rear-wheel models. All versions of the Super Duty trucks came equipped with four-wheel disc brakes.

On two-wheel drive F-250 and F-350 pickups, the Twin I-Beam independent front suspension with coil springs was used; their four-wheel drive counterparts were equipped with solid front axle (Dana 50 and Dana 60) with leaf springs. In 2005, the front suspension was updated as four-wheel drive trucks were converted to front coil springs; to reduce unsprung weight, the mounting of the front sway bar was changed to the frame instead of the front axle. The manual locking hubs on Super Duty trucks are made by Warn.[8]

On the F-250 and F-350, the rear suspension used heavy-duty 3" wide leaf springs and staggered shock absorbers; a standard stabilizer bar was included on dual rear-wheel models. Single-rear wheel versions were fitted with a 10.5-inch (270 mm) Sterling 10.5 axle 35-spline axle with choices of conventional or limited-slip differentials; initially developed for previous-generation Ford trucks, it was strengthened for use in the Super Duty. In dual-rear wheel F-350s, the rear axle was a Dana 80.

On F-450 and F-550 cab-chassis trucks, the Dana 60 front axle was replaced with a Dana Super 60 in 2005. The rear suspension on 2011-2014 F-450s Pickup used Dana 80 axles and 2008-2010 & 2015-2018 F-450s Pickup used Dana S 110. F-450 cab-chassis used a Dana S 110. F-550s used a Dana 135 from 1995 to 2004; in 2005, the Dana S 110 rear axle was added to the F-550.

The Dana 50 axle featured on most F-250 Super Dutys differs greatly from the early models. The Dana 50 started out as a Twin Traction Beam axle (much like independent suspension) in 1980. This lasted all the way to 1997 models. The Super Duty models then used a solid axle version of this axle. The ring, pinion, carrier and u joints all remained the same however. The Dana 50 was phased out of the trucks in 2004, in favor of the Dana 60 and was last used in the Ford Excursion.

Throughout its production run, the first-generation 1999-2007 Ford F-Series Super Duty was offered in three main trim levels:

The base XL was the "work truck" trim level of the F-Series Super Duty. Its standard features included a manual transmission, an AM/FM stereo with two front door-mounted speakers, a heater and blower, vinyl-trimmed seating surfaces with bench seats, steel wheels with black center hubs, black front and rear bumpers, a black "egg-crate" front grille, and manual windows and door locks. Optional features that were offered on this trim level included cloth-trimmed seating surfaces or vinyl-and-cloth-trimmed seating surfaces, power windows and door locks, an AM/FM stereo with cassette player (later, a single-disc CD player instead of a cassette player) and four speakers, chrome front and rear bumpers as part of an XL Decor Group, an automatic transmission, and air conditioning.

The mid-range XLT was the most popular trim level of the F-Series Super Duty. It added the following features to the base XL trim level: an AM/FM stereo with cassette player (later, a single-disc CD player instead of a cassette player) and four speakers, cloth-trimmed seating surfaces, bright center wheel hubs, chrome front and rear bumpers, a chrome "egg-crate" front grille with black inserts, power windows and door locks, and air conditioning. Optional features that were offered on this trim level included aluminum wheels, keyless entry (later, this option became standard equipment on this trim level), an AM/FM stereo with both a cassette player and a single-disc CD player (later, a six-disc, in-dash CD changer), an automatic transmission, and a power-adjustable front driver's bench seat.

The top-of-the-line Lariat was the most luxurious trim level of the F-Series Super Duty. It added the following features to the mid-range XLT trim level: an AM/FM stereo with both a cassette player and a single-disc CD player (later, a six-disc, in-dash CD changer), leather-trimmed seating surfaces, chrome-clad (later aluminum) wheels and center wheel hubs, keyless entry, a security system, electronic climate controls, a power front bench seat with fold-down center armrest, wood interior trim panels, and a chrome front grille with chrome inserts. Available options included two-tone exterior paint, color-keyed grille insert as well as front & rear bumpers, bucket seats replacing the bench seat, heated front seats, and an automatic transmission (which later became standard on this trim level).

There were multiple special edition Super Duty models that were offered.

For 2003, a special Centennial Edition Super Duty Crew Cab was offered to celebrate the 100th anniversary of Ford Motor Company. The truck could be ordered only as a Crew Cab, but a choice of bed lengths, DRW or SRW and gasoline or diesel engine were available. The Centennial Edition offered the following standard equipment: Monochromatic Black Clearcoat exterior, Premium Verona-grain Imola leather seating finished in Two-Tone Parchment, Special Centennial Edition badging and a commemorative keychain and wristwatch. The Centennial Edition also came with special leather-bound owners manual with the embossed signatures of Henry Ford, Edsel Ford, Henry Ford II, and William Clay Ford, Jr.[9]

Ford offered a special Harley-Davidson Super Duty truck from 2004-2007. Available only on SRW models, the Harley package could be had with either SuperCab or Crew Cab and customers could choose either V10 gas or 6.0L Powerstroke turbo diesel power. Based upon the Lariat trim, Harleys had a unique black leather interior, with the Bar and Shield logo adorning the front and rear captains chairs (SuperCab models had a rear bench). Heated seats, a leather-wrapped multifunction steering wheel, power adjustable pedals, and power-adjustable heated mirrors round out the standard equipment. Unique spun-metal gauge faceplates, embroidered carpeted floor mats, and a leather-wrapped console lid with individually serial numbered badging round out unique interior appointments. 2004 Harleys could be had with three unique paint schemes, Competition Orange/Black Clearcoat two-tone, Dark Shadow Gray/Black Clearcoat two-tone or a Black Clearcoat solid paint job. Unique pinstriping was found on all three color options.

In 2003 Ford began to offer its King Ranch trim package to the F-250 and F-350 Superduty trucks. This included rich Castaño leather seats, steering wheel audio and climate controls, front heated seats, 18” aluminum wheels (SRW) or 17” wheels (DRW), and an improved instrument panel.

2005 saw changes to the Harley package corresponding with the refresh of the F-250 and F-350 Super Duty model. No longer could you order a SuperCab Harley-Davidson and the 5.4L V8 was added as the base engine for the package. New unique black trimmed headlights, billet-style grille, and 20" wheels were made standard. Gone was the two-tone paint jobs, but optional was painted ghost flames. 2005 models could be had in two color options, Black or True Blue Metallic. The interior stayed largely the same, with luxurious black leather captains chairs in the front and rear and Harley Bar and Shield badging galore, but the truck saw the same interior updates as other '05 Super Dutys.

To bridge the gap between the pickup line and the much larger medium-duty F-650/F-750, Ford introduced the F-450 and F-550 variants of the Super Duty; with an available GVWR from 17,950-19,500 lbs, it pushes the Super Duty into the Class 5 truck market. Available only as a chassis cab for commercial upfitters, both versions were fitted with dual rear wheels.

While largely aimed at fleet buyers, F-450 and F-550 were configurable in XL, XLT, and Lariat trim levels available to Super Duty pickup buyers. The sole gasoline engine was the 6.8L V10 while the 7.3L PowerStroke was the diesel option; in 2003, this was replaced by the 6.0L PowerStroke.

In 2005, the F-450 and F-550 received further updates to the exterior than the rest of the Super Duty line, with an extended front bumper and front fenders; the F-550 received a "wide-track" front axle to sharpen its turning radius.

The Ford F-350 Super Duty first generation was also assembled in Venezuela as a commercial small truck from 1999 to 2010. For this market the F-350 featured the 5.4L V8 Triton engine, a 5-speed manual transmission, and a choice of 4x2 or 4x4.

Ford Super Duty trucks were built in Brazil, with different engines than its North American counterparts and fewer options, initially between 1999 and 2011, with a limited reintroduction of the F-350 in 2014. The dual-rear wheel variant of the F-350 is known locally as F-4000. They were widely exported to Australia (F-250 and F-350), South Africa (F-250) and Argentina (F-250, rebadged as F-100, and the F-350 DRW rebadged as F-4000), usually following the Brazilian specification (with an obvious change of the cockpit location in the versions targeted to Australia, South Africa and other RHD markets) but Australia had a wider range of options in pair with its American counterparts, including automatic transmission and the V8 engines.[10] Supercab extended-cab bodystyle was never officially available in Brazil and regional export markets (Uruguay and Argentina), but was made in RHD for export to Australia. South Africa had only the MWM engine and 5-speed manual transmission, with the option of 2WD and 4WD for the single-cab while the crew-cab had 4WD as standard.

This 2nd generation of Super Duty includes the F-250 Super Duty (starting at $22,380), F-350 Super Duty (starting at $24,025), and the all new F-450 Super Duty (starting at $39,205). The F-250 and F-350 Super Duty basically has the same payload and towing specs as the last generation.

The model lineup for the 2010 F-250 and F-350 Super Duty is the XL (starting at $25,300), XLT (starting at $28,845), Lariat (starting at $36,420), Cabela's (starting at $42,655), King Ranch (starting at $42,955), and Harley-Davidson (starting at $56,925).

The model lineup for the F-450 Super Duty is the XL (starting at $44,145), XLT (starting at $49,525), Lariat (starting at $52,965), King Ranch (starting at $56,955), and the Harley-Davidson (starting at $62,625)

The FX4 model, which was once just an optional Off Road 4x4 package that could be added to any model in the lineup, is replaced by the 4x4 Off Road Package. The FX4 became a model of its own. It still had the same specs as the previous generation but with more of a sporty trim package. The FX4 model has been discontinued for the 2010 model year and has been reverted to an optional Off Road 4X4 package.

• XL - Included: Vinyl upholstery, 5.4L Triton V8, 17" steel wheels with all-season tires, rear folding bench seat (XL Crew Cab), an AM/FM stereo with digital clock and 2 speakers, black vinyl floor covering, visors, sealed-beam halogen lamps, manual windows, manual locks, and manual side-view mirrors.

For 2008, Ford and Harley-Davidson once again joined forces to bring out a new special edition Super Duty. The Harley-Davidson package was available on both F-250 and F-350 Crew Cab SRW models. A gasoline engine was no longer offered with the package, instead, a 6.4L Powerstroke turbo diesel was standard. Unique black and dusted copper two-tone leather captains chairs with bar and shield logo, leather-trimmed center console, unique gauge cluster, and embroidered carpeted floor mats rounded out interior features. 20" wheels, billet-style grille, blacked out headlights, illuminated cab steps, power folding body-color Powerscope mirrors, rubber bed mat with Harley-Davidson logo and special badging were the exterior highlights. The truck could be ordered with two unique exterior themes, a black monochromatic look with bodyside graphics or a black and vintage copper two-tone with chrome dimensional boxside Harley-Davidson lettering. An Audiophile premium 8-speaker stereo with subwoofer was standard, while a DVD-based navigation system was optional. Rear seat DVD entertainment system with 8" screen was also optional, but could not be ordered with the power moonroof.

The Harley-Davidson package returned for 2009 with some changes. For the first time, the Harley-Davidson package was offered on the F-450 DRW pickup. The interior was trimmed in all black leather, instead of the two-tone for 2008. New colors were offered, Black with flame tape stripes, Black with Vista Blue painted flames or Dark Blue Pearl with Vista Blue painted flames. Ford's ToughBed spray on bedliner and a rearview camera were made options.

For 2010, only minor changes were made. Dark Blue Pearl was deleted from the color options in favor of Black with Tuxedo Black painted flames and the rearview camera was made standard. 2010 was the final year Ford offered a Harley edition Super Duty.

2009-2010 A special Cabela’s edition was available in the Crew Cab FX4 configuration. It featured special leather interior with Cabela’s logos embroidered in the seats, custom two tone paint options, a locking centre console, and a locking firearm storage under the rear seats.

The same two gas engines are carried over and rated exactly the same from the 2nd generation. The 3-valve 5,408 cc (5.408 L; 330.0 cu in) V8 SOHC is standard. The 3-valve 6,802 cc (6.802 L; 415.1 cu in) V10 SOHC was still a $699 option over the 5.4L V8. The 4-valve Navistar 6.4 L (6400 cc, 390.5 cu in) V8 OHV Power Stroke diesel engine was the diesel engine option and was a $6,895 option over the 5,408 cc (5.408 L; 330.0 cu in) V8.

Some unique points to highlight of the 2008, 2009 & 2010 F-450 with a regular production pickup bed, which was only offered as a chassis cab before. It has 2 available axle ratios of 4.30 and 4.88:1. The F-450 Super Duty with the optional 'High Capacity Trailer Tow Package' increases the GCWR from 26,000 to 33,000 lb (15,000 kg). Maximum payload is 6,120 lb (2,780 kg). Maximum towing is 24,500 lb (11,100 kg) (4.88 axle ratio) / 20,500 lb (9,300 kg) (4.30 axle ratio). It comes standard with Crew Cab, 8-foot (2.4 m) long bed, DRW (Dual Rear Wheels), Limited Slip rear axle, 10-lug 19.5-inch (500 mm) Forged wheels made by Alcoa, Trailer Tow package, and the TowCommand TBC (Trailer Brake Controller). The only engine offered in the F-450 Super Duty is the 6.4 L V8 Power Stroke Sequential turbo diesel. The F-450 is equipped with a standard 6-speed manual or optional 5-speed TorqShift automatic transmission.

The 2011 Ford Super Duty is available with either a gas or diesel engine. The gas option is an E85-capable 6.2 L 2-valve SOHC V8, which puts out 385 horsepower (287 kW) and 405 pound-feet (549 N⋅m) of torque under 10,000 lb GVWR, 316 hp and 397 lb/ft of torque over 10,000 GVWR.[20] The diesel is the new 6.7 L Power Stroke V8, producing 390 hp (291 kW) and 735 lb⋅ft (997 N⋅m) of torque.[21] The new engine is an entirely Ford product, unlike previous diesels, therefore reducing development costs and shipping delays. The 6.8-liter V10 was dropped from the regular Super Duty models, however it is still an option with the F-450 and F-550 chassis cabs, mated with a 5-speed automatic transmission.

Shortly after the unveiling of the 6.7 L Power Stroke V8, GM unveiled the 2011 Chevrolet Silverado and GMC Sierra 3500HD with Duramax 6.6-liter turbodiesel V8, making 397 hp (296 kW) and 765 lb⋅ft (1,037 N⋅m) of torque. Ford quickly responded by boosting the output of the Power Stroke just months after its initial release, to 400 horsepower (298 kW) and 800 lb⋅ft (1,100 N⋅m) of torque. For customers who purchased a Super Duty with the original Power Stroke V8, Ford offered a free upgrade at dealerships to the new level of output.[22] Power and torque was increased to 440 horsepower (328 kW) and 860 lb⋅ft (1,170 N⋅m) of torque on 2015 models.

No manual transmission is available in the United States, but in Mexico and Venezuela the F-350 is available with a 5 Speed Manual.[23] Automatic transmission features a manual mode. The diesel engine's transmission optionally features a PTO and is a "live-drive" unit. "Live-drive" meaning the PTO is directly connected to the engines crankshaft, whereas the GM's Allison 1000 transmission and Ram's Aisin use a torque converter or clutch (depending on being an automatic or manual, respectively).

On the 6.7 L diesel engine only, there are 2 separate cooling systems:

1. High-temperature system that runs at 194 degrees to cool the engine.
2. Low-temperature system with a 122-degree coolant for the following;

• fuel cooler
• EGR system

All engines will be paired with a "TorqShift" 6-speed automatic transmission, with the gasoline engines featuring 2 transmissions: 5-speed manual transmission (Chassis Cab F-350 Mexico Market only), Ford's all-new "TorqShift-G" automatic transmission.

The Super Duty will be available in eleven exterior color options.

On April 4, 2017, all Ford F-250 Super Duty trucks built between October 1, 2015 to April 1, 2017 were recalled due to the risk of improper and damaged rods in the parking brake and transmission allowing the truck to move while in park. This affected 52,000 trucks but no injuries or accidents were reported.[30]

Ford F-450

The 2020 Super Duty debuted at the 2019 Chicago Auto Show in February.[31] It features a revised grille and tailgate design, new wheel options, and higher-quality interior materials for the Limited trim. A new 7.3-liter gasoline engine is available. Nicknamed "Godzilla", it makes 430 horsepower and 475 lb-ft of torque. The 6.7-liter Power Stroke engine has been strengthened, bumping output to 475 horsepower and 1,050 lb-ft of torque. Ford's 10-speed automatic transmission is now available with the diesel and 7.3-liter Gasoline engines. The 6-speed is still available, but only for the F-250 with the 6.2-liter engine. Per customer request, the F-250's ride height has been decreased by two inches. Ride height in the F-350 and F-450 are unchanged.

For 2020, Ford is reintroducing the F-600, a name that was last used in the late 1990s on a medium-duty truck. Based on the F-550 Super Duty, the F-600 Medium Duty will feature the body and cab of a traditional Super Duty Chassis Cab, with upgrades to the chassis over and above the F-550. The F-600 chassis upgrades include upsized U joints, an alteration to the exhaust system to accommodate dynamic clearances for the larger U joint crosses, upgraded brakes, wider wheels (6.75" instead of 6") to support wider tires (245mm instead of 225mm) for increased tire load capacity. Geared towards fleet buyers who require the GVWR capacity of the heavier F-650 Medium Duty, though prefer the size and maneuverability of the smaller F-550 Super Duty. Available with either a 7.3L "Godzilla" gasoline V8 engine, or the 6.7L Powerstroke Turbodiesel V8 engine, paired with the "TorqShift" 10-speed automatic transmission and two-wheel-drive (4X2) or four-wheel-drive (4X4), the F-600 Medium Duty will go on sale in the middle of 2020.[32]

For 2020, Ford reintroduces the Tremor name for the F-250 and F-350 Super Duty pickups. The nameplate was last used on the 2014 Ford F-150 as a sport appearance package. As an off-road oriented version of the F-250 and F-350 Super Duty, the Tremor models will compete directly with the Ram 2500 Power Wagon, and will feature a suspension lift and upgraded tires and wheels from the factory. The trucks will also offer details not found on other Super Duty models, such as blacked out accents on the front grille, wheels, side emblems, and side mirrors, as well as 'Tremor' decals on the sides of the pickup box. Offered as a SuperCrew Cab model with a six-foot pickup box, and with four-wheel-drive (4X4), the Tremor will be equipped with the new 7.3L "Godzilla" gasoline V8 engine, while the 6.7L Powerstroke Turbodiesel V8 engine will be optional (the Ram 2500 Power Wagon only offers a gasoline V8 engine). The trucks will come equipped with 35 inch tall off-road tires, eighteen-inch matte black-painted alloy wheels, and a new 10-speed "TorqShift" automatic transmission. Crawl ratios will be 53:1 for gasoline-equipped models, while the ratio for diesel-equipped models will be 44:1. The trucks will be able to ford water up to 33 inches deep, and will feature up to 10.8 inches of ground clearance. Another new feature for all Super Duty models (including the Tremor), is the Trailer Reverse Guidance System, which is similar to the Pro Trailer Backup Assist system in the Ford F-150, and allows for the driver to easily back their truck up to a trailer with little effort. The all-new 2020 Ford F-250 and F-350 Super Duty Tremor models went on sale in the Fall of 2019.[33]

2004-2015 Ford F-750 Super Duty

In 2000, Ford returned to the Class 6-7 truck market as it expanded the Super Duty line into the medium-duty segment. They developed a joint venture with Navistar International known as Blue Diamond Trucks, the F-650 and F-750 Super Duty were assembled in Mexico. While the chassis and other components would be common to both manufacturers, Ford and International would each source their own bodywork and powertrain; the cab for the Ford trucks would be common with other Super Duty models.

For the 2016 model year, the medium-duty truck range was given a major upgrade, following the end of the joint venture and the shift of the production to the United States. In place of outsourced engines and transmissions, the 2016 F-650 and F-750 now use a 6.8L gasoline V10, a 6.7L PowerStroke diesel V8, and a 6-speed automatic transmission all supplied by Ford.

2001 Ford Excursion XLT

From 2000 to 2005, the F-250 Super Duty served as a basis for the Ford Excursion sport-utility vehicle. Along with Chevrolet Suburban (and its Cadillac/GMC/Holden counterparts) and the International Harvester Travelall, the Ford Excursion was one of the longest non-limousine sport-utility vehicles ever sold.

The Excursion was available in three trim packages, XLT, Limited, and top-of-the-line Eddie Bauer. It was offered in two or four wheel drive, and with three engine options: the 5.4L V8, the 6.8L V10, or the Powerstroke V8 Turbodiesel. The Excursion was only available with an automatic transmission.

While the Excursion was sold mostly in North America and Mexico, a similar vehicle was sold in Brazil from 1998 to 2012 as a second-party conversion of the Ford F-250 crew-cab (similar to the Centurion F-Series/Bronco conversions).

Lenco BearCat 4x4 armored personnel carrier

As a result of the heavy-duty frame and powertrain of its chassis, the Ford Super Duty has served as a donor platform for multiple types of armored vehicles, for civilian, law enforcement, and military use. Most versions are constructed using the Ford F-550 chassis cab. Examples include the Didgori-2, Lenco BearCat, Plasan Sand Cat, GAV Gurkha, APC Novator, and Conquest Knight XV.
