This PML cover for the big Ford trucks and SUVs has a traditional straight fin design. It adds capacity to help lower the differential fluid temperature. Thick walls and gasket flanges add strength to the differential housing and provide a uniform clamping force on the gasket surface for a secure seal.

This rear differential cover fits the 10¼ inch or 10½ inch Sterling rear end found on:

• Ford F-250, 1989 and newer
• Ford F-350 single rear wheel, 1989 and newer (if you have a Dually, see our Dana 80 cover)
• Ford Excursion

PML makes three different rear end covers for the Ford Sterling 10¼ and 10½ inch ring gear, 12 bolt differentials. They have the same prices but different fin patterns, shapes, sizes and features.

PML offers a matching front end cover. Please call for information.

This cover does not yet have a fill port but a fill hole will be available in the future. Please call or email us for details. Some trucks require a fill hole on the cover so check your stock set-up.

NOTE:

If you would like PML to machine your pan for a temperature sensor, there is an additional charge of $40. Please include temperature sensor size in the order notes, or you may order over the phone to insure accuracy. 888-832-5248

If a hole is needed for a temperature sensor, please call or email us for details.

Installations

Picture of patterned fin differential cover (part number 9513) on the Kelderman Screamin' Diesel project truck, a 2004 Harley–Davidson Super Duty F–350 pickup.

Click here for an article by The Diesel Garage showing the installation of patterned fin front and rear covers (part numbers 10816 and 10737) on an F–250. Image shows RTV on the gasket surface.

Richard's F–250 has a custom paint job on the body and he wanted a custom differential cover to match. Richard selected part number 10816 and matching front cover 10737 and did a custom powder coat in shiny red.

To give your pickup a custom look, buy an as-cast differential cover. We irridite our covers so on arrival they are clean and ready to install or to let you be creative as Richard did with his.
