The Ford Super Duty is a line of commercial pickup trucks (over 8,500 lb (3,900 kg) GVWR) introduced in 1998 for the 1999 model year. The F-250 to F-550 Super Duties are assembled at the Kentucky Truck Plant in Louisville, Kentucky, USA. The F-650 and F-750 Super Duties are assembled at the Blue Diamond Truck plant in Mexico.

The Super Duty trucks are larger, heavier built commercial/industrial 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. 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. This is because the '99 model year of the F-series has all the bolt holes in the frame for both two-wheel and four-wheel drive precut by the manufacturer.

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 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 Chevrolet Silverado HD and GMC Sierra HD were introduced.

These trucks were styled distinctly different for the first time from the smaller F-150 half-ton pickups. They did not share components with the F-150 platform at all (excepting V-8 gas engines), even though it was still considered an F-series truck. Instead of the aero look, it was more boldly angular with a raised hood and lowered fenders, somewhat like fender / hood medium truck style pioneered by the 1994 Dodge Ram pickup. As an industry first, 2 big massive complete ring-style front tow hooks were included. The side windows went lower forward in the door like a commercial medium to heavy duty truck (similar to a Kenworth "Daylight Door"), and the grille was also narrower and tall as if from a larger truck, and in 2001, optional manual telescoping Trailer Tow (TT) mirrors became available.

There were three cab options: Standard (2-3 passengers) with two doors, SuperCab (5-6 passengers) with 2 reverse-opening small rear doors (4 doors), and the crew cab with 4 full doors and seats for 4-6 people. The Super and Crew cabs came with 6 ¾-foot and 8-foot (2.4 m) full-size bed options, but the Standard cab was only available with the 8' bed. The F-250 Super Duty would also be the base platform for the short-lived Ford Excursion which was the only passenger SUV larger than the Chevrolet Suburban and its twin, the GMC Yukon XL.

The Ford Super Duty trucks are built in Brazil since 2003. Brazilian trucks were widely exported to Australia(F-250), South Africa and Argentina (where they were sold as the F-100).[1]

Engines Edit

The Super Duty had several available engines. A 2-valve per cylinder 5.4 L Modular V8 with 255 horsepower (190 kW) and 350 foot-pounds force (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 2V 5.4L V8 increased slightly from 255hp to 260hp. For the 2004-2008 model years, all models equipped with the 5.4L Triton received the 3V SOHC heads. Power was now rated at 300hp with 365 lb/ft of torque. The 7.3 Power Stroke turbodiesel with 235 horsepower (175 kW) and 500 foot-pounds force (680 N·m)of torque from 1999 to 2000 and upped to 250 hp (190 kW) and 500 ft·lbf (680 N·m) of torque in 2001 to 2002 trucks equipped with an automatic transmission or 275 hp (205 kW) and 520 ft·lbf (710 N·m) of torque for trucks equipped with a manual transmission.

6.0 Power Stroke Edit

The 6.0 Power Stroke with a variable-vane turbo was phased in starting in 2003; this engine produced 325 horsepower (242 kW) and 560 foot-pounds force (760 N·m) of torque. The 6.0 L 32-valve pushrod-actuated Power Stroke single-turbo diesel was modified in 2005, boosting torque to 570 ft·lbf (770 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 vehicle full buybacks (due to the Barneys Law), late 2006 was the last of the 6.0 L diesels.

Transmissions Edit

Four transmissions were available. A standard 5-speed manual for gasoline engines, a standard 6 speed for diesel engines, an optional 4R100 4-speed automatic for gas or diesel, and a 5-speed automatic for the 6.0 diesels. Trucks with the TorqShift 5-speed automatic are rated at exactly 1,000 lb (450 kg) higher towing capacity than trucks with the standard 6-speed manual transmission.

Torqshift 5R110Edit

The Torqshift 5-speed 5R110 automatic transmission replaced the 4-speed in the 2003 model year truck with 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.

Transfer case and 4x4 Edit

On 4x4 models there still is a choice of a New process(pre 99 250 and 350 used the borg warner 1356) 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. The 2005 F-250 Super Duty has an unusually large number of Complaints[2] referring to a "Death Wobble" in the front suspension. An investigation has pointed out that tire pressure is very critical although many complaints have posted that correct tire pressure was maintained. Aftermarket track bar kits can mitigate these effects and improve the ride.

Front suspension Edit

The front suspension on 4x4's use a solid front (monobeam) Dana 50 and Dana 60 axles on the F-250 and F-350 pickups. A Dana 60 is used on the F-450 and F-550's until the 2005. The 2005-2007 models use a Dana Super 60. Leaf springs eventually got switched to coils and a sway bar was added. The front suspension on 4x2 models is independent twin I-beam with coil springs on the F-250 and F-350 pickups. While a solid axle is used on F-450 and F-550 trucks. The manual locking hubs on Super Duty trucks are made by Warn [3]

F-250 solid axle Edit

The Dana 50 axle featured on most F-250 Super Duty's 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.

Rear suspension Edit

The rear suspension on all F-250 models and some F-350 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. While the other F-350 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 (dual rear wheel) models. An optional slide-in camper certification package with heavier springs and an optional stabilizer bar package are available on SRW (single rear wheel) 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.


Facelift (2005–2007) Edit

Ford F-350 King Ranch -- 09-12-2010

2005–2007 Ford F-350 King Ranch crew cab

The Super Duty line was restyled for 2005. Exterior styling was given a minor update with a new front end, however, with this facelift came significant changes both in mechanics and options offered.

Major changes over the previous generation of Super Duties includes increased payload (GVWR) and towing (GCWR) capacities, a new taller front grille, revised interior, standard locking tailgate, 10-17% thicker partially boxed frame, alternator with a higher current capacity, larger-than-before 4-wheel disc brakes (13.66-in front and 13.39 in (340 mm) rear rotors) with new two-piston calipers, revised engines, new automatic transmission options, a new optional built-into-dash Ford TowCommand TBC (Trailer Brake Controller) that is fully integrated with the truck's PCM (Powertrain Control Module) and ABS (Anti-lock Braking System), optional dashboard-integrated auxiliary "upfitter" switches (for adding off road lights, winches, snow plows, etc.), and an optional drivers side glove compartment.

The two previous gas engines were upgraded from 2 valve per cylinder to 3 valve (2 intake and 1 exhaust) per cylinder designs. The standard 5.4 L V8 produces 300 horsepower (220 kW) and 365 foot-pounds force (495 N·m) of torque, and the optional 6.8 L V10 produces 362 hp (270 kW) and 457 ft·lbf (620 N·m).

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.

Two transmissions were made available for the redesigned 2005-2007 models. The standard M6OD 6-speed manual overdrive and the optional heavy duty TorqShift 5R110W 5-speed automatic overdrive with Tow/Haul mode which replaced the 4-speed 4R100 used in the first generation.

Ford offers a PTO (power take-off) which provides direct engine power for accessory equipment without the expense and installation time of separate, independently mounted electric motors or other power sources. The standard equipment 6-speed manual transmission comes with an integrated PTO. The optional TorqShift 5-speed automatic 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).

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. Depending on model and options, the empty title curb weight is 6,000-8,000 lb.

Approximate payload capacities are 3,000 lb (1,400 kg) for the F-250, 4,000 lb (1,800 kg) for the F-350 with single rear wheels, and 5,800 lb (2,600 kg) for the F-350 with dual rear wheels. This generation of Super Duties has exactly double the payload capacity as compared to the older traditional (non-Super Duty) F-250 and F-350 trucks. By direct American comparison to the F-250 SD the Chevrolet Silverado 2500HD/GMC Sierra 2500HD is rated at 2,600 lb (1,200 kg) max and the Dodge Ram 2500 Heavy Duty is rated at only 2,100 lb (950 kg) max payload capacity.

Approximate towing capacity for the F-350 Super Duty is 19,200 lb (8,700 kg) max. By direct American comparison Dodge Ram 3500 Heavy Duty is rated at 16,400 lb (7,400 kg) max and Chevrolet Silverado/GMC Sierra 3500HD is at 16,500 lb (7,500 kg) max.

The second-generation Super Duty was to debut for 2007, but quality issues pushed it back to a 2008 model.[4] The new 2008 model features an all-new 6.4 L (6400 cc, 390.5 cu in) twin-turbo Power Stroke Diesel V8 with piezo fuel injectors to replace the problematic 6.0 L Power Stroke single-turbo Diesel V8.[5] The new engine is said to produce 350 hp (260 kW) and 650 ft·lbf (880 N·m) of torque.[6]

After investing $95 million in the Kentucky plant on various upgrades and modernizations, Ford began production of the 2008 Super Duty trucks on December 18, 2006. However, the truck didn't go on the market until January 2007. 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 levelsEdit

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.

EnginesEdit

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 is still a $699 option over the 5.4L V8.[5]

6.4L Power Stroke Edit

The 4-valve Navistar 6.4 L (6400 cc, 390.5 cu in) V8 OHV Power Stroke twin-turbo diesel (PSD) engine (350 hp and 650TQ) was the diesel engine option until it was replaced in the 2011 model year with a Ford designed 6.7L diesel engine. It was a $6,895 option over the 5,408 cc (5.408 L/330.0 cu in) V8.

F-450Edit

Some unique points to highlight of the all new 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 (Gross combined weight rating) 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). 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) wheels, Trailer Tow package, and the TowCommand TBC (Trailer Brake Controller). The only engine offered in the F-450 Super Duty will be the all new 6.4 L V8 Power Stroke twin-turbo diesel. The F-450 is equipped with a standard 6-speed manual or optional 5-speed TorqShift automatic transmission.


Facelift (2011–present)Edit

2011 Ford F-250 XLT -- 07-10-2010

2011 F-250 XLT

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.

EnginesEdit

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.[7] The new engine is an entirely Ford product, unlike previous diesels, therefore reducing development costs and shipping delays.

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 software upgrade at dealerships to the new level of output.[8]

When equipped with the 6.7 L Power Stroke the F-450 is able to tow 24,400 pounds (11,100 kg) and has a maximum payload of 5,200 pounds (2,400 kg). The F350 has 22,600 pounds (10,300 kg) of towing capacity and 7,070 pounds (3,210 kg) of payload. Each engine is mated to a 6R140 heavy-duty TorqShift six-speed automatic transmission.[9]

Class 2 pickup trucksEdit

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 [10]

Class 3 pickup trucksEdit

Ford has two class 3 pickup trucks. The normal F-350 and F-450 (13,050 GVW). The F-450 remains available in class 4 as well. The class 3 F-450 has a wider wheelbase despite having the same axles as the F-350.
