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

This Wehrli differential cover kit includes the fabricated aluminum cover, stainless steel hardware, and a drain plug. It's built for the 11.5-inch AAM rear axle found on many Chevrolet Silverado, GMC Sierra, Dodge Ram, and Ram heavy-duty trucks from 2001 through 2019. A differential cover might not seem like a big deal, but it's crucial for keeping your axle fluid clean and preventing leaks. This cover offers a solid upgrade over the stock unit.

Constructed from fabricated aluminum, this cover is lighter than a cast iron replacement and resists corrosion. It features a custom two-stage powder coating in WCFab Grey for a durable finish that looks good. The included stainless steel hardware ensures it won't rust over time, and the drain plug makes servicing your rear differential much easier. Having a drain plug means you can drain the old fluid without having to remove the entire cover, simplifying oil changes.
