Wehrli 01-19 Chevrolet Duramax/03-19 Dodge Cummins 11.5in AAM Rear Diff. Cover - Deore Gold

When you're looking to upgrade the rear differential on your heavy-duty truck, this fabricated aluminum differential cover from Wehrli Custom Fabrication is a solid option. It's built specifically for the 11.5-inch AAM rear axle found on many Chevrolet Duramax and Dodge Cummins models from the early 2000s through 2019. This cover not only helps protect your differential but also gives your truck a custom look with its unique Deore Gold two-stage powder coating.

This cover is constructed from aluminum, making it lighter than a stock steel cover. It's fabricated for a strong, well-built unit that can handle the rigors of heavy-duty use. Included with the cover are stainless steel hardware for installation and a drain plug, which makes servicing your differential much easier. Having a drain plug allows you to drain the old gear oil without having to remove the entire cover, simplifying fluid changes.

This differential cover fits a wide range of GM and Dodge trucks, including models like the 2001-2019 Chevrolet Silverado 2500 HD and 2003-2010 Dodge Ram 2500. It's a direct replacement for your factory cover, meaning it fits right without needing modifications.
