Greenlight 1:64 2019 Ford F-350 Lariat: Blue Jeans

The Ford F-Series Super Duty (often shortened to Ford Super Duty) is a series of trucks manufactured by Ford Motor Company. Introduced in 1998 for the 1999 model year, the F-Series Super Duty trucks marked the addition of a heavy-duty pickup to the Ford F-Series range with the new versions of the F-250 and F-350 pickups, while the previous 1987–1997 F-Super Duty chassis cabs were replaced by the F-450 and F-550 Super Duty.

The Super Duty trucks utilize a distinct chassis from the lighter F-150, with heavier-duty chassis and suspension components to allow for higher payload and towing capacities; additionally, the product line continued the use of Ford PowerStroke diesel engines. With a GVWR over 8,500 lb (3,900 kg), Super Duty pickups are class 2 and 3 trucks while chassis cab trucks are class 4 and class 5. The F-Series Super Duty has been used as the base chassis of the Ford Excursion full-size SUV.

Ford F-250 to F-550 Super Duty trucks are assembled at the Kentucky Truck Plant in Louisville, Kentucky, while medium-duty F-650 and F-750s are assembled at Ohio Assembly in Avon Lake, Ohio (prior to 2016, medium-duty trucks were assembled in the Blue Diamond Truck joint venture with Navistar in Mexico). As of 2016, 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 Suriname, even though traffic is on the left side of the road, the import and registry of left hand drive vehicles is allowed. In Australia, it was officially imported in right hand drive from Brazil between 2001–06, however as of 2007, Ford no longer offers the Super Duty in Australia.

On September 24, 2015, Ford unveiled the 2017 Ford Super Duty line at the 2015 State Fair of Texas. This marks the first all-new Super Duty line since their 1998 debut, the frame is made from 95% high strength steel and the body (like the F-150) is made from high-strength military grade aluminum alloy.

For the first time since 1999, both the Super Duty and F-150 lines are constructed using the same cab[26] to better compete with GM, Ram and Nissan's HD trucks. In a major departure, the stand-alone front grille and stepped front fenders seen since 1998 were eliminated from the exterior. The 2-bar grille introduced in 2011 was widened, integrating the headlights into its design.

In a switch to an aluminum-intensive body similar to the F-150, Ford created a potential 700 lbs (318kg) of weight savings; in spite of the addition of heavier-duty frame and driveline components, the 2017 Super Duty weighs in at up to 350 lbs (159kg) less than comparable 2016 models. Ford strengthened the frame and drivetrain with fortified drive shafts, axles, brakes and the 4WD transfer case.[26] F-250 and F-350 pickups are built on a fully boxed frame; chassis-cab models are produced on a frame boxed up to the rear of the cab and of C-channel design rearward.

For 2017 production, the Super Duty line shares its powertrain lineup with its 2016 predecessor: a 6.2L gasoline V8, 6.8L V10 (F-450 and above), with a 6.7L diesel V8 available in all versions. The 6.2L gasoline V8 engine remains at 385 hp but torque rises from 405 lb-ft to 430 lb-ft. Additionally, the gasoline V8 produces its max torque at over 700 rpm less than the previous 405 lb-ft engine. The 6.7L diesel engine also remains at the same 440 hp (323kW) but torque increases from 860 lb-ft upwards to 925 lb-ft. The diesel engine now produces its peak torque at 1,800 rpm instead of the previous 1,600 rpm. The F-250 receives a TorqShift-G six-speed automatic while all other Super Duty trucks are paired with the 6R140 6-speed automatic. Crew Cab models will have a 34-gallon (128l) tank for the 6.75-foot bed and 48-gallon fuel tank for the 8-foot bed.

The interior design of the all-new Super Duty is similar to that of the 2015 Ford F-150, and shares many of the F-150's components.

Trim levels will continue to be XL, XLT, Lariat, King Ranch, and Platinum. The Limited trim would not debut for F-250 and F-350 until 2018. Cab configurations continue to be 2-Door Regular Cab, 4-Door Super Cab, and 4-Door Super Crew Cab (the F-450, in pickup truck configuration, is only available in this configuration), with Short Box (6' 9") and Long Box (8') bed lengths. The truck will be available in F-250, F-350, and F-450 pickup truck models, and F-350, F-450, and F-550 chassis cab models. All will be available in both 4X2 and 4X4 configurations. The F-350 will be the only model available in either Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configurations, the F-450 and F-550 will only be available in a Dual Rear Wheel (DRW) configuration, and the F-250 will only be available in a Single Rear Wheel configuration. Base prices in the U.S. range from $32,535 (F-250 XL) to $77,125 (F-450 Platinum). Full pricing is available on the manufacturer's website.

In September 2017, Ford announced that the 2018 F-450 would be the first $100,000 pickup truck, with the addition of the new Limited trim, which debuted on the Ford F150.
