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

What you get with this Wehrli differential cover is a well-built, fabricated aluminum housing designed to replace the stock cover on your 11.5-inch AAM rear axle. It comes in a striking Brizzle Blue finish, thanks to a custom single-stage powder coating, and includes stainless hardware along with a drain plug for easier maintenance. This cover is built for a range of heavy-duty trucks, including models like the 2015 Chevrolet Silverado 2500 HD and the 2012 Ram 3500.

This isn't just about looks; the fabricated aluminum construction offers improved durability over a stock stamped steel cover. The added capacity can also help keep your differential fluid cooler, especially under heavy loads. The inclusion of a drain plug is a practical touch that makes servicing your rear differential much simpler, allowing you to drain the old fluid without having to remove the entire cover.

When you're looking to dress up your rear end and add a bit more robust protection, this Wehrli differential cover is a solid option. The Brizzle Blue powder coat is applied over a fabricated aluminum body, giving you a strong and attractive upgrade for your truck's drivetrain.
