Dissipates Heat and Extends Service Life

PPE designed their Heavy-Duty Cast Aluminum Rear Diff Cover to greatly decrease oil temperatures, minimize friction and maximize lubrication. Featuring an increased fluid capacity which improves thermal stamina, an internal heat sink and external cooling fins all of which help dissipate heat. Your differential oil will run cooler and retain its viscosity, and in turn extending service life.

Heavy Duty Construction with Magnetic Fill Plug

Crafted of high grade A356.0-T6 aluminum, PPE's Rear Differential Cover is built to withstand anything thrown its way. Each diff cover comes complete with a Neodymium magnetic fill plug to catch and trap harmful magnetic particles, preventing potential damage.
