PML offers three versions of a rear end cover for Ford Sterling 10¼" and 10½" differentials.

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)

Click here for an article by The Diesel Garage showing the installation of this differential cover (fin pattern P/N 10816) and our Dana 50/60 Front cover (P/N 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.
