The Ford F-450 was a variant of the 4th Gen F-Series Super Duty that was introduced for the 2017 model year. The F-450 Super Duty was a heavy-duty truck that was built in a crew cab pickup body style with the long truck bed or a cab-chassis body style. The main powerplant available on the 4th Gen F-450 was the 6.7L 'Powerstroke' V8 diesel engine, although cab-chassis was available with a 6.8L V10. From 2020, a new 7.3L 'Godzilla' V8 engine was added the lineup. Depending on the year, a 6 or 10 speed automatic transmission was offered with drive going to the dual rear wheels. Production of the 4th Gen F-450 ended in 2022, when it was replaced by the 5th Gen Ford F-450 Super Duty.
