Description
This is a black aluminum finned differential cover built for Ford 10.25" and 10.5" 12-bolt rear axle housings — two heavy-duty Ford rear ends that share the same 12-bolt cover pattern, allowing one cover to serve both axle sizes. This makes it a common fitment across a wide range of Ford truck and SUV applications including F-150, F-250, F-350, Bronco, and Excursion builds.
The finned aluminum construction dissipates heat more effectively than a flat steel factory cover, helping reduce gear oil temperature during towing, hauling, and sustained performance use. A black finish adds show-quality appearance for builds where underbody aesthetics matter alongside heavy-duty function.
A drain plug is included. Gasket and mounting hardware are not included — confirm your sealing method (cut gasket or RTV) and source hardware separately before installation. Verify your specific axle model, housing shape, cover bolt pattern, and suspension clearance before ordering. Sold individually.
One Black Aluminum Cover Fits Both the Ford 10.25" and 10.5" Axle
This finned black aluminum cover fits both the Ford 10.25" and Ford 10.5" 12-bolt rear axle housings, which share the same cover bolt pattern — giving you a single cover solution across two of Ford's most common heavy-duty rear ends used in F-series trucks, Bronco, and Excursion builds.
Finned Aluminum Dissipates Heat on Heavy-Duty Tow and Haul Applications
Unlike a flat steel factory cover, the finned aluminum design increases surface area to help dissipate heat from gear oil during sustained towing, hauling, and off-road use — conditions where Ford 10.25" and 10.5" axles are most commonly operating at their limits. Aluminum construction also reduces unsprung weight compared to a steel cover.
