Your Ford SuperDuty looks great after you got those extra couple inches lifted on your truck but now your old dirty rear axle has more of an appearance than you were planning. Get a fresh cool new look as well as a more functional diff cover with Wehrli Custom Fabrication's 12 Bolt Aluminum Cover! The Wehrli Custom Fab Ford F250/F350 Sterling 10.5" 12-Bolt Rear Differential Cover is built for Power Stroke owners who demand durability, sealing performance, and a custom look that stands out.

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

Constructed from fabricated aluminum, this heavy-duty diff cover delivers increased strength and rigidity over stock while helping protect your ring and pinion from hard use whether you’re towing, daily driving, or pushing big horsepower builds.

Unlike factory stamped covers, this WCFab unit features a precision O-ring seal for a leak-free installation and includes stainless steel hardware for long-term corrosion resistance.

And because looks matter too, each cover is finished in your choice of custom powder coat colors, giving your truck a clean, high-end finish that matches the rest of your build.

Why Upgrade Your Differential Cover?

Your differential takes a beating especially under towing, hauling, or high horsepower. Upgrading to a heavy-duty aluminum differential cover helps improve protection, maintain proper sealing under load, and extend the life of your gears and bearings.
