The Sterling Differential cover is designed with pure function in mind. Like all of the Kryptonite Series Diff Covers the Sterling diff cover is fabricated with 1/4 inch steel plate for the cover and has 3/8 inch steel ring for the base. With a 3/8 inch thick steel ring the cover is built to resist "peel up" as you drag your diff over rocks and other terrain. The Sterling cover does not have a fill plug. The fill plug is located in the differential housing. All diff covers are shipped unpainted. We can add a fill plug in the cover for a small fee.
This cover was designed for use with our truss systems to reinforce the truss to the diff.
