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 includes our exclusive high-power Neodymium magnet-equipped fill plug to pull harmful ferrous metal particles out of the oil before they have a chance to attack the bearings and gears.
