Off-road trails are never easy on your undercarriage. Unexpected boulders, deep ruts and downed trees can bang, bash and bruise your vulnerable components—especially your rear end. Protecting your pumpkin just got a whole lot easier, thanks to B&M Differential Covers. Constructed from cast T6 aluminum, these burly bolt-ons reinforce your rear end to fend off case distortion and deflection of your ring gear and cap bearing.

Hard knocks aren’t the only threat to your rear end. High heat can be just as deadly. That’s another reason why B&M Diff Covers are made from aluminum. Not only do they dissipate heat better than old-school iron, but they’re also oversized to hold more oil. More fluid and a more advanced metal—they both add up to lasting protection.

Whether you’re shredding the trail in a Jeep or cruising through town in a Chevy, you’re sure to find a B&M Differential Cover to fit. They come in a wide range of sizes to fit the most popular differentials, from a Dana 30 to a Ford 8.8. Your BM Differential Cover also includes a magnetic drain plug, all mounting hardware and a 1-Year Warranty.

Fits perfect no RTV needed just bought a OE diff gasket from advance auto LOOKS GREAT!! Allows more fluid and helps keep the rear end cooler than stock. Installs less than 2 hours with beer would recommend to anyone looking for a upgrade to their differential
