PPE differential covers are made in the USA from high-quality cast aluminum for strength and optimum heat dissipation. Combined with the largest set of cast cooling fins in the industry, found both inside as well as outside the pan, PPE’s differential covers offer outstanding fluid cooling capabilities not often matched. This cover also holds an extra quart-and-a-half of fluid, offering a bit of added thermal stamina to the rear-end gears on those long hauls.

To keep the fluid clean, PPE includes a high-powered Neodymium-magnet-equipped fill plug to pull metal particles right out of the oil before they have a chance to attack the gears and bearings.

Features: ▪ Internal and external cooling fins ▪ Neodymium magnet equipped fill and drain plugs ▪ Natural finish increases heat transfer.
