2020-2024 L5P Duramax Differential Cover

This rear differential cover has been meticulously engineered to minimize friction and maximize lubrication of your gear set. If you want to keep your differential gears running cool and clean, look no further. Our cover is made from high-quality cast aluminum for optimized strength and heat dissipation.

An increased fluid capacity provides a higher thermal stamina. This new cover is outfitted with internal heat sinks and external cooling fins that increase the cover's surface area aid in dissipating heat. By doing this, we help keep your differential oil running cooler which will help keep its viscosity which in turn helps extend differential fluid life and increase time in between services.

We have also provided a fill plug equipped with a high power magnet which will aid in keeping fluid cleaner.
