Chronology
Predecessor Ford F-250/350 (1992–1997)

The Ford Super Duty is a line of trucks (over 8,500 lb (3,900 kg) GVWR) that were launched by Ford in early 1998 for the 1999 model year. The F-250 to F-550 Super Duties are assembled at the Kentucky Truck Plant in Louisville, Kentucky. The F-650 and F-750 Super Duties were assembled at the Blue Diamond Truck plant in Mexico prior to 2014, when production was shifted to Avon Lake, Ohio.

The Super Duty trucks are larger, heavier built series pickup trucks with heavier-duty body-on-frame steel ladder frames, axles, springs, brakes, transmissions, more powerful engines, and all other heavier/bigger components (with much higher payload and towing capacities) than the older traditional equivalent F-250, F-250HD (Heavy Duty), and F-350 Ford truck lines (where from 1987 to 1997 the F-250, F250HD, F-350, and F-Super Duty were all chassis cab models only). The two-wheel-drive and four-wheel-drive model frames are the same in the F-250 and F-350 series, making conversion from a two-wheel-drive model to a four-wheel-drive model less difficult than in other truck models. F-350 chassis cab, F-450 and F-550 frames and suspension are the same between the two-wheel-drive and four-wheel-drive models. The trucks were once under investigation by the National Highway Traffic Safety Administration for steering failures, but the investigation revealed the failures were driver error and had nothing to do with design.[3]

Origins of name

In 1960, Ford re-branded the heaviest-GVWR versions of the F-Series (F-950) as Super Duty models; these were powered by the Ford gasoline engines of the same name.[4] In 1963, the Super Duty name reappeared on the gasoline-engined variants of the N-Series trucks.[5]

On the F-Series line, the Super Duty name first appeared as the "F-Super Duty" in 1987 on Class 4 chassis-cab models.

For the 1999 model year, Ford shifted the F-250 and F-350 truck lines to a design mechanically and cosmetically distinct from that of the F-150. The F-350 was not available for 1998, while a lighter-duty version of the F-250 was available that year with the F-150's body. By using 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 main competition, General Motors, followed suit for the 2001 model year, when the GMC Sierra 3500 was introduced.

For the first time, larger trucks utilized a design distinct from the smaller F-150 half-ton pickups. Although considered part of the F-Series, the Super Duty trucks shared no common body components aside from their taillights; under the skin, only the 5.4L V8 was shared. The front was more boldly angular with a raised hood, similar to the Dodge Ram. As an industry first, 2 large complete ring-style front tow hooks were included. The side windows dropped lower forward in the door like a commercial medium to heavy duty truck (similar to a Kenworth "Daylight Door"), the grille was narrower and taller as if from a larger truck, and optional manual-telescoping trailer tow mirrors were available.

There were three cab options: Regular cab (2–3 passengers) with two doors, SuperCab (5–6 passengers), which included two small "suicide" doors at the rear, and the Crew Cab (5-6 passengers) with four full doors. The Super and Crew cabs came with 6 3⁄4-foot (2.1 m) and 8-foot (2.4 m) full-size bed options, but the regular cab was only available with the 8-foot bed. The F-250 Super Duty would serve as the base platform for the Ford Excursion which was the only passenger SUV larger than the Chevrolet Suburban and its twin, the GMC Yukon XL.

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.[7]

Powertrain

Engines

The Super Duty had several available engines.

A 2-valve-per-cylinder 5.4 L Modular V8 with 255 horsepower (190 kW) and 350 ft·lbf (470 N·m) of torque was standard, while the 2-valve-per-cylinder 6.8 L Modular V10 with 310 horsepower (230 kW) and 425 ft·lbf (576 N·m) of torque was an option. In 1999, power output for the 16V 5.4L V8 increased slightly from 255 hp to 260 hp. For the 2005–2008 model years, all models equipped with the 5.4L Triton received the 3V SOHC heads. Power was now rated at 300 hp with 365 lb/ft of torque.

Similarly, the MY2005 Triton V10 received 3-valve heads and output was raised to 362 hp (270 kW) and 457 lb·ft (620 N·m).

7.3 Power Stroke

The 7.3 Power Stroke turbodiesel with 235 horsepower (175 kW) and 500 ft·lbf (680 N·m) of torque from 1999 to 2000 and upped to 250 hp (190 kW) and 525 ft·lbf (712 N·m) of torque in 2001 thru first-quarter 2003 trucks equipped with an automatic transmission or 275 hp (205 kW) and 525 ft·lbf (712 N·m) of torque for trucks equipped with a manual transmission.

6.0 Power Stroke

The 6.0 Power Stroke with a variable-vane turbo was phased in starting in the second quarter of 2003; this engine produced 325 horsepower (242 kW) and 560 ft·lbf (760 N·m) of torque. The 6.0 L 32-valve pushrod-actuated Power Stroke single-turbo diesel was modified in 2004, boosting torque to 580 ft·lbf (790 N·m), but power remained the same as the previous version with 325 horsepower (242 kW). Due to impending tighter emissions requirements, along with a very high warranty exposure and over 500 full vehicle buybacks (175 by one northern California law firm alone),[8] 2007 models were the last to include the 6.0 L diesel.

Transmissions

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 420 ft-lbs of torque, while later s5-47 versions were rated to 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) higher towing capacity than trucks with the standard 5/6-speed manual transmission. The 6-speed manual transmission comes with an integrated PTO.

Torqshift 5R110

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 a spin-off style, mounted on the passenger-side exterior of the transmission. 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).[9]

Transfer case and 4x4

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, limited-slip rear differential, 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.

Suspension

The front suspension on four-wheel drive F-250 and F-350s are equipped with solid front (monobeam) Dana 50 and Dana 60 axles. Prior to 2004, a Dana 60 was used on F-450 and F-550s; 2005–2007 models use a Dana Super 60. Leaf springs eventually got switched to coils for the 2005 model year and the front sway bar was relocated to a frame mounting location, instead of being part of the front axle's unsprung weight. The front suspension on two-wheel drive trucks is independent twin I-beam with coil springs on the F-250 and F-350 pickups, while a solid axle is used on F-350, F-450 and F-550 cab chassis trucks. The manual locking hubs on Super Duty trucks are made by Warn.[10]

The rear suspension on all F-250 and F-350 SRW (single rear wheel) models use a 10.5-inch (270 mm) Sterling 10.5 axle 35-spline axle with choices of conventional or limited-slip differentials in 3.73, 4.10, and 4.30:1 ratios. The Sterling axle was upgraded for the Super Duty trucks. The ring gear was increased from the 10.25 inches to 10.50 and the carrier was upgraded with three pinions instead of two. Disc brakes were made standard. F-350 DRW models use a Dana 80. All models have heavy duty 3" wide leaf springs and staggered shock absorbers. A standard stabilizer bar is included on DRW (Dually) models. An optional slide-in camper certification package with heavier springs and an optional stabilizer bar package are available on SRW models. The rear suspension on F-450 trucks used Dana 80 axles while F-550 models used a Dana 135 until 2005 models. 2005–2007 models use a Dana S 110 axle.

F-250 solid axle

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.

The Super Duty line was restyled for 2005, with the exterior and interior receiving minor updates. The dashboard, gauges, headlights and badges were all updated, and a new, taller front grille, a revised interior and a standard locking tailgate were also added. Significant changes were also made to both the drivetrain and available options.

Major changes over the previous generation of Super Duty trucks include increased payload (GVWR) and towing (GCWR) capacities.

Fuel tank capacities are 38 U.S. gallons in the 8' long bed models, and 29 U.S. gallons in the 6.75' short bed models. Depending on models the optional trailer tow hitch receiver comes with a 2" or 2.5" Class V receiver and 4- and/or 7-pin wiring harness in either 12,500 or 15,000 lb (6,800 kg). All Super Duties include factory installed external oil and transmission coolers.

Fail-Safe Cooling System

Ford's "Fail-Safe Cooling System" is designed to protect the engine due to loss of coolant. If the engine overheats, it will automatically switch from 8/10-cylinder (depending on V8 or V10 engine) operation to alternating 4/5-cylinder (depending on V8 or V10 engine) operation. Because there is now 50% less hot combustion, the engine will operate cooler. The vehicle will continue to operate, but with very limited engine power. The now so-called 'dead' cylinders also act like an air pump to cool the engine down even more. This system allows the driver to travel a short distance to obtain service or to reach a repair facility. The distance that can be traveled depends upon vehicle load, outside temperature, and current road conditions.

F-450/F-550

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 second-generation Super Duty was to debut for model year 2007, but quality issues pushed it forward to the 2008 model year. It features an all-new 6.4 L, 390.5 cu in Power Stroke Diesel V8 with piezo fuel injectors and sequential turbos to replace the problematic 6.0 L Power Stroke single-turbo Diesel V8. The new engine produces 350 hp (260 kW) and 650 ft·lbf (880 N·m) of torque.[13] The vehicle had its first official showing at the Texas State Fair in 2006.

Located near the same dash area as the last generation (but slightly to the right and more directly below the radio), this generation of Super Duty has the same Ford TowCommand TBC (Trailer Brake Controller) and 4 AUX Upfitter switches as the last generation set-up.

There is an optional concealed slide-out step and swing-up hand grab bar in the rear tailgate for easy access.

Ford introduces its all new optional "Rapid-Heat Supplemental Cab Heater," only available on Super Duty trucks with the Diesel engine and TorqShift automatic transmission. In the winter, it quickly raises the cabin temperature to a comfortable level until the engine is warm enough to handle the job.

Trim

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.

Powertrain

The same 2 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.[14] 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.

F-450 Pickup

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 Super Duty line received a large exterior upgrade that includes a new, bigger front fascia. Its engines were also upgraded to better compete with the new Silverado HD and Ram HD. Ford stated in the 2011 Chicago Auto Show that the 2011 trucks have the thickest gauge steel frame of any Heavy Duty truck. The 2011 Ford F-Series Super Duty was awarded Truckin's "Topline Pulling Power" award for 2011. It also won Popular Mechanics best workhorse of 2011, and the best "Gear of the Year" in the trucks category. The F-450 is able to tow 24,400 pounds (11,100 kg) and has a maximum payload of 4,920 pounds (2,230 kg). The F350 has a maximum 21,600 pounds (9,800 kg) of towing capacity and 7,110 pounds (3,230 kg) of payload.[17] Each engine is mated to a 6R140 heavy-duty TorqShift six-speed automatic transmission.[18] The Ford F-250, the F-350 and the F-450 all come with trim levels including the XL, XLT, Lariat, King Ranch, and Platinum.[19]

The 3rd generation of the Ford Super Duty Trucks are assembled at Ford's Kentucky Truck Plant, with additional production for other countries in Venezuela and Mexico. In Venezuela the F-350 super duty is offered as a commercial use small truck cutaway featuring a 6.2L V8 gas engine with a 5-speed manual tremec transmission TR-4050 with a choice of 4x2 or 4x4 wheel drive. Since 2012 due to government regulations, the Venezuelan F-350 Super Duty is factory equipped to use both natural gas and gasoline. The F-250 super duty was also recently re-introduced in this market after ten years. It is being marketed using the same engine as the Venezuelan F-350, but only with a 6-speed automatic transmission, 4x2 or 4x4 wheel drive option in both single and double cab configurations.

A feature unique to the 2011 Super Duty is the addition of a locking differential. It is only available for the F-250 and SRW F-350 4x4 models with a rear Sterling 10.5 axle. It is a 390.00 USD option[20] The diesel F-250 relies on vacuum-boost brakes, while the F-350 relies on Hydro-boost. Both gas versions of the F-250 and SRW F-350 use vacuum-boost. F-250 is a class 2 truck. While the F-350 SRW, F-350 DRW, & F-450 pickup are class 3. The F-250 and F-350 (SRW & DRW) have 13.66 inch front brakes and 13.39 inch rear brakes. The 2015-2016 F-250 and F-350 have 14.29 inch vented disc brakes on the front and rear axles as an improvement made for these model years. The F-450 pickup has 14.53 inch front brakes and 15.35 inch rear brakes. The F-450 has a wider track than the F-350. The F-450 remains available in class 4 as a Chassis Cab truck.

Powertrain

Engines

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. 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.

Transmission

No manual transmission is available in the United States, only an automatic but it 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 Torqshift 5R110, GM's Allison 1000 transmission and Ram's Aisin use a torque converter or clutch (depending on being an automatic or manual, respectively).

Cooling System

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
  • transmission fluid
  • air-to-water inter-cooler

A belt-driven pump mounted low on the driver side circulates the high-temperature coolant, while a separate belt-driven pump mounted higher on the passenger side circulates the low-temperature coolant.

F-450 pickup

The F-450 pickup is available only in a single configuration; a crew cab with a dual rear-wheel 8-foot bed. The only powertrain combination is the 6.7 L Powerstroke turbodiesel V8 mated to the six-speed TorqShift automatic transmission. Trims include the XL, XLT, Lariat, King Ranch, and Platinum

Chassis cab

The Ford Chassis cabs were updated using the new 2011 body style. Ford chassis cabs are still rated up to the industry maximum 19,500 pound Gross Vehicle Weight Rating. The Gross Combined weight was upped 2,000 pounds to 35,000 lb maximum; 5,000 pounds greater than the nearest competitor.[23]

Fourth generation (2017–present)

On September 24, 2015 Ford unveiled the new Super Duty at the 2015 State Fair of Texas. This marks the first all-new Super Duty line since their 1999 debut, the frame is made from 95% high strength steel and the body like the F-150 is made from aluminum. Ford strengthened the frame and drivetrain with fortified drive shafts, axles, brakes and the 4WD transfer case. The new Super Duty weighs up to 350 lbs less than previously.[24]

Variants

Medium-duty trucks (F-650 and F-750)

Main article: Ford F-650

In 2000, Ford returned to the Class 6-7 truck market as it expanded the Super Duty line into the medium-duty segment. Developed in a joint venture with Navistar International, 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 supplied by Ford.

Sport-utility vehicles

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 variants) and the International Harvester Travelall, the Excursion is the longest non-limousine sport-utility vehicle ever sold.

As of 2015, the Ford Super Duty is sold in the United States, Canada, Mexico, Venezuela (F-250 and F-350), Suriname, Brazil (F-350/F-4000), Argentina (F-4000 only), Angola (F-250 and F-350), Cambodia, the Middle East, and Iceland (F-350 only) in LHD only. In Australia, where it was officially imported in RHD from Brazil until 2005, newer American-built units can be imported but must be converted locally to RHD. In Suriname, even though traffic is on the left side of the road, the import and registry of LHD vehicles is allowed.
