Wehrli 01-19 Chevrolet Duramax/03-19 Dodge Cummins 11.5in AAM Rear Diff. Cover - Fine Texture Black

Wehrli Custom Fabrication is known for building tough parts for heavy-duty trucks. This differential cover is a prime example, designed to protect the rear axle on a wide range of popular pickups. It fits 11.5-inch AAM rear axles found on Chevrolet Silverado and GMC Sierra trucks from 2001 to 2019, as well as Dodge Ram and Ram trucks from 2003 to 2018. If you're looking to upgrade from a stock cover or replace a damaged one, this is a solid option.

This cover is fabricated from aluminum, making it lighter than a stock steel unit and resistant to rust. It's finished in a fine texture black powder coat that holds up well against road debris and the elements. The fabrication process means it's a well-built piece that can handle the stresses of towing and hauling. It also includes a drain plug, which makes servicing your rear differential much easier. You'll want to have the proper tools and refer to the manufacturer's instructions for installation, as it involves removing the old cover and ensuring a good seal with new RTV sealant.
