PPE Power 138051210 Features:
Specially engineered to minimize friction and maximize lubrication. Keep your GM rear differential running cool and clean with an upgraded cover from PPE. Made from high-quality cast A356.0-T6 aluminum for strength and optimum heat dissipation.
The increased fluid capacity provides greater thermal stamina. This keeps your differential oil running cooler. The oil will keep its viscosity which helps extend differential service life. This new cover also has specially engineered internal rib structures that minimize friction, maximizes lubrication, and increases rigidity.
To help keep your differential oil cleaner, this cover comes with PPE Billet Stainless Steel Drain/Fill Plugs. Each plug features high-power Neodymium magnets which pull harmful ferrous particles out of your fluids before they have a chance to do damage. Simply wipe grit away at each service.
