Help keep your rear differential running cool and clean with an upgraded differential cover from PPE. 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 industry-leading fluid cooling.

This pan also holds additional fluid, offering thermal stamina for those long hauls.

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

Comes with stainless steel fasteners and a CMP - 4000 high-performance gasket to make installation a quick and painless job.

The PPE 138051020 Heavy Duty Differential Cover for your 2001-2016 GM Duramax is cast from A356-T6 aluminum alloy, and prolongs life of rear differential gears by reducing oil temperature. Robust side ribs provide additional strength. Includes 3/8" NPT stainless steel drain plug and 1" sight level.
