Want a way to spruce up your rear differential while also upgrading it at the same time? Grab a color that matches your truck's style with an easy to use fill plug and tough aluminum construction. If you're running a Ford Super Duty, chances are you're putting serious load on your rear axle. Whether it's towing, hauling, or making big power the work your truck is doing requires constant maintenance. The Wehrli Custom Fabrication Dana M275 14-Bolt Rear Differential Cover is built to handle it all while adding a clean, custom look to your truck.

NOTE: While some colors are kept in stock, other colors will take an extra 10-15 business day delay in powder coating.

Designed specifically for trucks equipped with the Dana M275 rear axle (10.8” ring gear), this fabricated aluminum cover provides superior strength over the factory stamped steel unit while helping protect your ring and pinion under heavy use.

Unlike OEM covers that rely on RTV sealant, this WCFab diff cover uses a precision O-ring seal for a consistent, leak-free installation. Combined with stainless steel hardware, it’s built to stand up to harsh conditions and long-term use.

Finished in your choice of WCFab custom powder coat colors, this cover not only protects your drivetrain it elevates the look of your entire build.
