PPE 138051300 Rear Heavy-Duty Aluminum Diff for 72-13 GM K1500 8.5" 10-Bolt

Keep your GM rear differential running cool and clean with an upgraded cover from PPE. Made from thick, high-quality A356.0-T6 cast aluminum for strength and optimum heat dissipation.

The beefy PPE differential cover is equipped with internal heat sinks and external cooling fins which increase the pan's surface area as well as thermal stamina. It keeps your differential oil running within its ideal viscosity range, helping extend differential service life.

To help keep oil cleaner, PPE includes our exclusive fill and drain plugs featuring high-power Neodymium magnets that trap and hold ferrous metal particles that are harmful to the gears.
This product is backed by our limited lifetime warranty.
