2020-2022 GM Duramax 6.6L L5P Differential Covers
While the stock differential cover on your 2020-2022 GM 6.6L Duramax L5P works fine for basic everyday applications, it certainly doesn't do the best protecting your differential during high-performance driving conditions. Here at Alligator Performance, you can pick up an aftermarket differential cover to keep your gears shielded from contaminants like dirt and water, as well as rocks and other obstacles encountered when off-road. A new differential cover is also great for dissipating heat faster over stock, preventing any potential damage to your Sierra or Silverado's differential. In addition to the premium protection these covers provide, each one of these aftermarket upgrades offer easy and immediate access for changing gear lube, taking away any additional maintenance hassles that burden your adventures.
