PPE Heavy Duty Front Differential Cover

Fits 2011-2022 Chevy/GMC 2500/3500 HD

Help keep your 2011+ GM truck’s front axle running cool and clean with an upgraded differential cover from PPE. 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 fluid cooling capabilities not often matched. This pan also holds an extra quart and a half of fluid offering a bit of added stamina on those long hauls. To keep the fluid clean, PPE installed its exclusive high powered Neodymium magnet equipped fill plug will pull metal particles right out of the oil before they have a chance to attack the bearings. Comes with Stainless Steel fasteners and a CMP - 4000 high performance gasket to make installation a quick and painless job.
