Ford Super Duty
Encyclopedia
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 (except V-8 gas engines), even though it was still considered an F-series truck. Instead of the aerodynamic look, it was more boldly angular with a raised hood and lowered fenders, somewhat like the 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 taller 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 5-6 people. The Super and Crew cabs came with 6 ¾-foot and 8 feet (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 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 with a 5 speed manual transmission with a choice of 4x2 or 4x4.
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).
with 310 hp and 425 ft.lbf of torque
was an option. In 1999, power output for the 16V 5.4L V8 increased slightly from 255hp to 260hp. For the 2005-2008 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. Similarly, the 2005+ Triton V10 received 3-valve heads and output was raised to 362 hp (270 kW) and 457 lb·ft (620 N·m). The 7.3 Power Stroke turbodiesel
with 235 hp and 500 ft.lbfof torque from 1999 to 2000 and upped to 250 hp and 500 ft.lbf of torque in 2001 to 2002 trucks equipped with an automatic transmission or 275 hp and 520 ft.lbf of torque for trucks equipped with a manual transmission.
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 1000 lb (453.6 kg) higher towing capacity than trucks with the standard 6-speed manual transmission. The 6-speed manual transmission comes with an integrated PTO.
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. 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).

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-350, F-450 and F-550 cab chassis trucks. The manual locking hubs on Super Duty trucks are made by Warn
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 discontinued for the trucks in model year 2004, in favor of the Dana 60 and was last used in the Ford Excursion.
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. F-350 DRW models use a Dana 80
. All models have heavy duty 3" wide leaf spring
s and staggered shock absorbers. A standard stabilizer bar
is included on DRW 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.
. However, with this facelift came significant changes both in mechanics and options offered.
Major changes over the previous generation of Super Duties include increased payload (GVWR
) and towing (GCWR
) capacities, 10-17% thicker partially boxed frame, alternator with a higher current capacity, larger-than-before 4-wheel disc brake
s (13.66-in front and 13.39 in (340 mm) rear rotors) with new two-piston calipers, revised engines, 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. 17 inch wheels are now standard instead of 16 inch wheels. Forged
Alcoa
wheels are still an option as well. 18 inch wheels are also an option on single rear wheel trucks.
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 hp and 365 ft.lbf of torque, and the optional 6.8 L V10
produces 362 hp and 457 ft.lbf.
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 15000 lb (6,803.9 kg). All Super Duties include factory installed external oil and transmission coolers.
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 of torque. 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.
The 2010 Super Duty was awarded 'Best Resale Value Truck".
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.
OHV Power Stroke diesel engine was the diesel engine option and was a $6,895 option over the 5408 cc V8.
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 33000 lb (14,968.5 kg). Maximum payload is 6120 lb (2,776 kg). Maximum towing is 24500 lb (11,113 kg). It comes standard with Crew Cab, 8 feet (2.4 m) long bed, DRW (Dual Rear Wheels), Limited Slip rear axle, 10-lug 19.5 inches (495.3 mm) Forged rims

and Ram HD
. 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 24400 pounds (11,067.7 kg) and has a maximum payload of 4920 pounds (2,231.7 kg). The F350 has a maximum 21600 pounds (9,797.6 kg) of towing capacity and 7110 pounds (3,225 kg) of payload.Each engine is mated to a 6R140 heavy-duty TorqShift six-speed automatic transmission.
, which puts out 385 hp and 405 lbft of torque. The diesel is the new 6.7 L Power Stroke V8, producing 400 hp and 800 lbft of torque. 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 and 765 lbft of torque. Ford quickly responded by boosting the output of the Power Stroke just months after its initial release, to 400 hp and 800 lbft 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.
No manual transmission is available in the United States, only an automatic. The diesel engine's transmission features a PTO and is a "live-drive" unit. "Live-drive" meaning the PTO is directly connected to the engines crankshaft, where as the Torqshift 5R110, GM's Allison 1000 transmission
and Ram's Aisin
use the Torque converter

. 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 There are mechanical differences between the F-250 and SRW F-350, despite looking identical. 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 pick up are class 3. F-350 SRW rear axle has thicker axle tubes. The F-250 and F-350 (SRW & DRW) have 13.66 inch front brakes and 13.39 inch rear brakes. The F-450 pick up 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 well.
The F-450 pick up is available in only one configuration while the F-250 and F-350 are available in multiple configurations. The Dana Super 60 is the front axle used in this truck. Previously the Dana Super 60 was used only as a Medium Duty axle.

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.Second generation (2008–2010)
The second-generation Super Duty was to debut for model year 2007, but quality issues pushed it back to a 2008 model. The new 2008 model features an all-new Power StrokeFord Power Stroke engine

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
