2001-2019 GM / RAM HD 11.5"-14 Bolt Heavy-Duty Cast Aluminum Rear Differential Cover
Made from high-quality cast A356.0-T6 aluminum for strength and optimum heat dissipation. PPE’s differential covers 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.
This part is not compatible with certain 06-12 Dodge Ram HD trucks equipped with Anti-Spin Differential Rear Axle due to the Tone Ring Sensor. For these trucks, refer to P/N 138051000.
