Differential Covers for Trucks, Jeeps & Performance Cars

Differential Covers for Trucks, Jeeps & Performance Cars

Differential covers protect the ring gear, bearing caps, and gear oil inside your axle housing. Upgrading from a factory stamped-steel cover to a cast iron, billet aluminum, or fabricated steel unit adds extra fluid capacity for better cooling and provides significantly more impact protection on trails and tracks.

Popular Diff Cover Upgrades

Top sellers include Dana 44 and Dana 60 covers from Yukon Gear and ARB, deep-sump covers for GM 8.5-inch and 10.5-inch axles, high-clearance covers for Jeep JL and JK axles, and aFe Power COVER axle covers for Ford F-150, Ram, and GM truck platforms. Many billet covers add fill-plug temperature ports for monitoring fluid temps under tow.

Do aftermarket diff covers actually help?

A thicker-walled cover increases gear oil capacity by one to two quarts on most axles, reducing operating temperature under sustained load like towing or trail driving. Reinforced covers also resist rock strikes that would crack or bend a stock stamped unit, keeping your differential sealed in the field.

What finishes are available for diff covers?

You can find raw cast iron, powder-coated black, polished billet aluminum, and machined finishes. Select a finish based on your build style and whether corrosion resistance or appearance is the priority for your application.
