2021 Ford F-350 problems

ford logo

The Ford Super Duty (also known as the Ford F-Series Super Duty) is a series of heavy-duty pickup trucks produced by the Ford Motor Company since the 1999 model year. Slotted above the consumer-oriented Ford F-150, the Super Duty trucks are an expansion of the Ford F-Series range, from F-250 to the F-600. The F-250 through F-450 are offered as pickup trucks, while the F-350 through F-600 are offered as chassis cabs.

Rather than adapting the lighter-duty F-150 truck for heavier use, Super Duty trucks have been designed as a dedicated variant of the Ford F-Series. The heavier-duty chassis components allow for heavier payloads and towing capabilities. With a GVWR over 8,500 lb (3,900 kg), Super Duty pickups are Class 2 and 3 trucks, while chassis-cab trucks are offered in Classes 3, 4, 5, and 6. The model line also offers Ford Power Stroke V8 diesel engines as an option.

Ford also offers a medium-duty version of the F-Series (F-650 and F-750), which is sometimes branded as the Super Duty, but is another chassis variant. The Super Duty pickup truck also served as the basis for the Ford Excursion full-sized SUV.

The Super Duty trucks and chassis-cabs are assembled at the Kentucky Truck Plant in Louisville, Kentucky, and at Ohio Assembly in Avon Lake, Ohio. Prior to 2016, medium-duty trucks were assembled in Mexico under the Blue Diamond Truck joint venture with Navistar International.
