The Heavy-Duty DEEP Aluminum Rear Differential Cover from PPE for GM trucks is designed to keep fluid cool, dense, and clean with cutting-edge features like internal heat sinks, external cooling fins, and a high-powered Neodynium magnet. The heat sink and cooling fins give the pan a larger surface area, resulting in cooler, denser liquid, and also prolonging the differential service life. The magnet filters out harmful metal particles, cleaning the oil and protecting the bearings and gears from damage. This cover is made in the USA from high-quality cast aluminum and features a pre-tapped 1/8-inch NPT port for temperature probe. Offering an additional quart of extra fluid capacity and extra strength to gear housing, this cover is available in three finishes: raw, brushed, and black.
