PPE Heavy Duty Rear Differential Cover 138051210 (Brushed) Compatible with 2020+ GM 1500 3.0L Duramax or 2014+ GM 1500 (V6 or V8 Gas)

PPE's Heavy Duty Rear Differential Cover 1380512xx is equipped with internal heat sinks and external cooling fins, increasing the pan’s surface area helping dissipate heat faster than the stamped steel stock differential cover. This makes for cooler and denser fluid, which lubricates better and helps extend differential service life.To keep the fluid clean, PPE installed its exclusive high-power Neodymium magnet-equipped billet stainless steel fill plug that pulls harmful ferrous metal particles out of the oil before damage occurs to the bearings and gears. A drain plug is also included for quick and easy servicing. Available in three finishes: Raw (PPE 138051200), Brushed (PPE 138051210), or Black (PPE 138051220)Covered by a limited lifetime warranty.
