2001-2024 Duramax 2500/3500HD New Style Rear Differential Cover - PPE

Made from high-quality cast A356.0-T6 aluminum for strength and optimum heat dissipation. PPE’s differential covers (Rear Differential Cover RAM/GM) offer industry-leading fluid cooling. Equipped with internal heat sinks and external cooling fins, increasing the pan’s surface area helps dissipate heat. This makes for a much cooler and denser oil. The cool, dense fluid lubricates better, which will extend differential service life.

To keep the fluid clean, PPE installed its exclusive high-powered Neodymium magnet-equipped fill plug that pulls harmful ferrous metal particles right out of the oil before they can attack the bearings and gears.
