    • Jeep CJ 5 rear, 1976 to 1985
    • Jeep CJ 7 rear, 1976 to 1985
    • Jeep Truck rear, 1981 to 1984

    • Muscle cars such as the 1968 AMC AMX-R

    Check your vehicle for fitment and clearance. Configurations vary. On some CJs, the gas tank is very close to the stock cover, leaving no room for a heavy duty aftermarket differential cover.

    Construction of PML Cover

    PML differential covers are aluminum, which is a great material for heat dissipation. For rock crawling and offroading, cast iron and steel are strong and protective of the differential internals although these metals are not good at heat dissipation. Aluminum is a much softer metal and a PML cover would need a shield or cage for off roading or rock crawling.

    Fill/Level Check Hole

    This cover was designed for vehicles with a a plug on the driveshaft side of the differential where filling and level check is done. As with the stock cover, this PML cover does not have a fill/level check hole.
