The Ford F-350 was a variant of the 4th Gen F-Series Super Duty that debuted for the 2017 model year. The F-350 Super Duty was a heavy-duty truck that was built in standard, extended (SuperCab), and Crew Cab passenger configurations, with short or long truck bed options. The standard gasoline engine was the 6.2L 'Boss' V8, but an optional 6.7L 'Powerstroke' V8 diesel option. From 2020 onwards a new 7.3L 'Godzilla' V8 was optional. Over the course of production a 6 or 10 speed automatic transmission was offered, with power going to the rear or all wheels depending on specification, and for customers who desired, dual rear wheels could be specified. Production of the 4th Gen F-350 ended in 2022, when it was replaced by the 5th Gen Ford F-350 Super Duty.
