Q&A
What axle does this cover fit?
Ford 10.5" 12-bolt rear axle housings, found on F-250 Super Duty, F-350 Super Duty, and Ford Excursion.
Will this fit a Ford F-250 or F-350 Super Duty?
Yes, the Ford 10.5" rear axle was commonly used in F-250 and F-350 Super Duty applications — confirm your specific axle model before ordering.
Will this fit a Ford F-150 or Fox Body Mustang?
No — the F-150 and Fox Body Mustang use smaller Ford rear axles (8.8" and 7.5" respectively), not the 10.5" 12-bolt.
Will this fit a GM rear axle?
No, this cover is sized for Ford 10.5" 12-bolt housings and is not compatible with GM axle families.
Does this come with a gasket or drain plug?
No — gasket, drain plug, and mounting hardware are not included.
Should I use a cut gasket or RTV to seal this cover?
Confirm your axle's sealing requirements — both cut gasket and RTV are commonly used depending on application and builder preference.
What material is this cover made from?
Steel with a chrome finish.
Can this be used on a towing or hauling build?
Yes, this is a common replacement cover for F-250, F-350, and Excursion builds used for towing and hauling.
What should I verify before installing this cover?
Confirm axle model, cover bolt pattern, ring gear size, housing shape, gasket or RTV sealing requirements, fill plug configuration, fluid fill level, and suspension clearance before installation.

Ford 10.5" 12-Bolt Chrome Steel Differential Cover
This is a chrome steel differential cover built for Ford 10.5" 12-bolt rear axle housings — the heavy-duty rear end used in Ford F-250 and F-350 Super Duty trucks and Ford Excursion. It's a direct-fit replacement for the factory differential cover on compatible Ford 10.5" axle housings, giving you a clean chrome appearance and solid housing protection for towing, hauling, and performance Super Duty builds.
Steel construction with a chrome finish supports durable sealing and housing protection, and is a common upgrade or replacement on Super Duty builds where a worn, leaking, or rusted factory cover needs to be replaced without a full axle service.
A drain plug, gasket, and mounting hardware are not included — confirm your gasket style (cut gasket or RTV), fill plug configuration, and suspension clearance before installation. Always verify your specific axle model and housing shape before ordering. Sold individually.
Chrome Steel Cover Built for Ford 10.5" 12-Bolt Super Duty Axle Housings
Manufactured from steel with a chrome finish, this differential cover is sized and bolted for Ford 10.5" 12-bolt rear axle housings, giving you a durable, clean-looking replacement for a leaking, rusted, or damaged factory cover on F-250, F-350, and Excursion builds.
Protects Gear Oil and Rear End Internals on Heavy-Duty Tow and Haul Builds
A cracked, warped, or leaking differential cover can allow gear oil to escape, leaving ring and pinion gears under-lubricated during heavy towing or hauling cycles. This chrome steel cover helps restore a solid seal on compatible Ford 10.5" housings, protecting rear end internals under the higher loads these axles are built to handle.
