Installation Notes

Clean the differential cover and housing flange thoroughly before installation. Verify axle model, bolt-hole count, and ring gear size before ordering, since this gasket is specific to Dana 60 and Dana 70 applications with a 10-bolt cover pattern. Confirm front or rear axle placement against the vehicle listing, especially on Ford F-350, Dodge Ram 2500/3500, and Chevrolet/GMC heavy-duty models.
