Applications

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.

Installation on Ford Tow Vehicle

This PML differential cover was installed on a Ford dynamometer test trailer axle. The test trailer is a mid-90s towing dynamometer. Ford uses it to simulate grades on a level surface. They tow this trailer behind a vehicle and can simulate a loaded trailer climbing any grade in the world. Our thanks to Jim for the pictures and for choosing a PML rear differential cover to cool down this test rig.
