Ford F-250 Differential Cover - Rear - Wehrli - Dana M275 - Illusion Purple - 17-24. A fabricated aluminum rear differential cover finished in Illusion Purple for 2017–2024 Ford F-250/F-350 SRW trucks equipped with the Dana M275 axle.

Built by Wehrli Custom Fabrication, this cover is designed for the M275 with 4" OD axle tubes and a 10.8" ring gear. It uses the 14-bolt pattern—verify your bolt count, as some F-250 models came with 12- or 14-bolt axles depending on tow package. F-250 with the HD Towing Package and all 2017+ F-350 SRW typically use the M275. Not compatible with DRW (dually) or High Output models. Aluminum construction, an O-ring seal, stainless hardware, and an integrated fill plug deliver reliable sealing and easy service.
