Product Details
Wehrli Custom Fabrication is known for making well-built parts for high-performance diesel trucks. This differential cover is a solid option for your 11.5-inch AAM rear axle, found in many Chevrolet, GMC, Dodge, and Ram heavy-duty trucks from 2001 through 2019. It's designed to replace your stock cover, offering improved protection and a custom look for your drivetrain.
This cover is fabricated from aluminum, which is lighter than steel and resists corrosion. It's finished in a Bengal Grey powder coat, giving it a tough look that stands up to road debris and the elements. The kit includes stainless steel hardware for a clean installation and a drain plug, making fluid changes much simpler than with a factory cover. This makes it easier to keep your rear differential running smoothly.
If you're looking to dress up your rear end or just want a more robust cover for your heavy-duty truck, this Wehrli differential cover is a practical choice. It fits a wide range of popular models, including the 2001-2019 Chevrolet Silverado 2500 HD and 2003-2010 Dodge Ram 2500.
