    • Ford F-250, 1989 to 2016, 2017 and newer models with 12 bolt stock cover, for 14 bolt cover, see PML Dana M275,14 Bolt Cover
    • Ford F-350 single rear wheel, 1989 to 2016, some 2017 and newer models (if you have a Dually, see PML Dana 80 differential covers)
    • Ford Excursion, 2000 to 2005

    Always check your vehicle to verify differential and space available for a larger cover. Because configurations vary, PML cannot guarantee fitment.

    2017 and later F250 trucks with 14 Bolt Rear Differential Cover: In 2017 Ford introduced heavy duty option with a Dana M275 rear differential. The stock cover for the Dana M275 has 14 bolts, not 12 like the Ford 10.25/10.5 cover. See PML Dana M275,14 Bolt Cover.

    Customers have installed this PML differential cover on hundreds of Ford F-250 and F-350 trucks and Excursion SUVs.
