Ford F-Series Super Duty 4th Generation

2017–2022 · P558 · truck

First clean-sheet Super Duty since the 1999 original. Aluminum body, fully boxed steel frame. 6.2L Boss V8 (2017-2019) replaced 2020+ by the 7.3L Godzilla gas V8 (430hp/475 lb-ft) — pushrod, port-injected, designed for fleet durability. 6.7L Power Stroke diesel updated in stages: 440hp/925 lb-ft (2017-2019), 475hp/1050 lb-ft (2020+). 6R140 carries through 2019; 10R140 10-speed from 2020. Tremor off-road package added 2020.

Watch out: 2020-2022 6.7L Power Stroke CP4 high-pressure pump is still the failure mode — dirty fuel or running the tank dry sends pump debris through the rails and injectors. $8,000-12,000 to clean up. Common preventive fix is a CP4 bypass kit returning unused fuel to the tank instead of through the pump. Also: 10R140 10-speed harsh-shift / shudder TSBs early in the run, addressed by Ford TCM reflashes.
