Rear Differential Cover - Heavy-Duty Cast Aluminum - RAM 2500-3500
Specially engineered to minimize friction and maximize lubrication. Keep your RAM rear differential running cool and clean with an upgraded cover from PPE. Made from heavy-duty cast A356.0-T6 aluminum for strength and optimum heat dissipation.
Increased fluid capacity provides increased thermal stamina. This thick 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-equipped fill plug that will pull harmful ferrous metal particles out of your oil before damage occurs.
Covered by a limited lifetime warranty.
