Ford 9.75" 12-Bolt Fiber Differential Cover Gasket

This is a fiber differential cover gasket sized and punched for Ford 9.75" 12-bolt rear axle housings. It's a direct replacement for a leaking, damaged, or missing cover gasket on compatible Ford 9.75" axle applications, providing a reliable fiber seal between the differential cover and the axle housing sealing rail.

The Ford 9.75" rear axle is commonly found in F-150, Ford Expedition, Lincoln Navigator, and Ford Explorer Sport Trac builds — making this gasket a common service item for routine differential cover removal, fluid changes, or cover upgrades on these platforms.

This gasket is sold individually and includes no hardware, cover, or drain plug. Confirm your axle model and cover bolt pattern before ordering, and clean the cover and housing sealing surfaces thoroughly before installation for a proper seal.

 

Fiber Gasket Cut for the Ford 9.75" 12-Bolt Cover Pattern
This fiber differential cover gasket is punched to match the 12-bolt pattern of Ford 9.75" rear axle housings, giving you a clean, leak-resistant seal between the differential cover and the axle housing sealing rail during cover reinstallation or replacement.

Stops Gear Oil Leaks at the Cover Sealing Surface
A worn, crushed, or damaged cover gasket is one of the most common causes of gear oil seepage at the rear axle. This fiber gasket compresses evenly across the cover sealing rail to help restore a consistent seal and stop leaks without requiring RTV compound, though RTV can be used in combination depending on your preference.
