Ford 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.
