A-Premium 9.75" Rear Differential Cover for 9.75in Ring Gear — Steel Housing with Gasket & Internal Magnet

The A-Premium 9.75-inch ring gear rear differential cover is a direct-replacement steel housing that includes a gasket and internal magnet to protect and seal the rear differential on compatible Ford and Lincoln models.

This heavy-duty replacement cover is engineered to restore a leaking or damaged rear differential housing and to help keep ferrous debris trapped before it circulates in the gear oil. Designed specifically for 9.75" ring gear housings and non–limited-slip (open) differentials, this unit installs in place of the original cover and uses the factory bolt pattern for a precise fit. It ships with a pre-cut gasket for a straightforward seal and a built-in magnet to collect metal particles.

How do I confirm this cover fits my vehicle?

Measure your differential's ring gear diameter or compare your OE part number to the listed cross-references. This cover is made for 9.75" ring gears and does not fit 8.8" or 10.25" housings. It also requires a non–limited-slip differential.

• Verify ring gear diameter: 9.75 inches required
• Not compatible with limited-slip differentials
• Check OE numbers: BL3Z4033C, F75Z4033AA, 697705, 111106

What hardware and sealing components are included?

The package arrives with a pre-cut gasket and an internal magnet fitted to the cover to help attract metallic residue. Bolts are not supplied, so reuse the factory hardware or purchase replacement differential cover bolts separately. There are 12 bolt holes matching the factory bolt pattern.

• Gasket included for immediate installation
• Internal magnet captures metal particles
• 12 bolt holes; bolts sold separately

Who is this for: This A-Premium 9.75" rear differential cover is intended for DIY mechanics, commercial fleet technicians, and owners of compatible Ford or Lincoln trucks and vans who need a reliable replacement for a leaking, damaged, or corroded rear cover. It's ideal when you require a direct-fit part with a gasket and magnet included, but remember to verify ring gear diameter and that your vehicle does not use a limited-slip differential before purchasing.
