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.

Increased fluid capacity provides increased thermal stamina. This new cover is equipped with specially designed internal heat sinks and external cooling fins which increase the pan’s surface area helping dissipate heat. This keeps your differential oil running cooler, the oil will keep its viscosity which helps extend differential service life. 

To help keep fluid cleaner, PPE includes our exclusive fill plug featuring a high-power Neodymium magnet that will pull harmful ferrous metal particles right out of your oil before they have a chance to do damage.
