PML makes two different covers for Ford trucks, like Ranger, and cars with the 7½ inch differential. One has a straight fin design and the other has a patterned fin design. The are also slightly different sizes (check dimensions on each webpage). Please check your vehicle before ordering.

Both of these PML rear diff covers add capacity to help lower the differential fluid temperature. Thick walls and gasket flanges add strength to the differential housing and provide a uniform clamping force on the gasket surface for a secure seal.


This rear end differential cover fits many Ford Rangers and and other Ford vehicles with a 7½" ring gear. Some common applications are:

  • Bronco II, 1984 to 1990
  • Ranger, 1983 to present (the 4.0L engine Rangers usually have the larger 8.8 inch rear)
  • Mustang, 1982 to 1986
  • Aerostar, 1986 to 1997 and minivans
  • Mazda B2300, 1994 and newer
  • Mazda B3000, 1994 and newer

This cover may also fit some minivans, Crown Vics, Grand Marquis cars, and Thunderbirds. Some models may have the larger Ford 8.8 differential, which is more rectangular in shape and longer (vertically). The Ford 8.8 stock cover is about 11 inches vertically and the 7.5 inch is about 9.75 inches vertically. Please check carefully which differential your vehicle has and if you have clearance.

Check out our Ford 8.8 diff cover for pictures and more information if you have the larger differential.

PML makes two designs for the Ford 7½ inch rear end to accommodate a variety of preferences and vehicles.
