Protect the rear differential of your Jeep Wrangler JL with the ARB 0750012B Differential Cover. Designed for M220 rear axles in Sport, Sahara, and Rubicon models, this heavy-duty cover helps shield the differential housing, ring and pinion gear set, and ARB Air Locker from impacts caused by rocks, trails, and other off-road obstacles. It is engineered for demanding competition and extreme off-road applications where differential protection is essential.

The ARB differential cover features a durable iron construction that adds strength to the axle housing while helping protect critical internal components. Its computer-optimized cross-brace design provides additional support and contributes to prolonged carrier bearing life. The cover’s profile is optimized to help preserve approach and departure angles, while recessed tensile cap screws and a low-profile drain plug help reduce the risk of damage when navigating difficult terrain.

A practical dipstick design places the magnet at the end for convenient inspection and maintenance. High-quality neodymium magnets help capture metallic particles in the differential fluid, supporting cleaner lubrication and improved service monitoring. Finished with a durable black powder coat, this ARB cover combines long-lasting protection with a clean appearance. The ARB 0750012B is a direct-fit differential protection upgrade for compatible 2018–2020 Jeep Wrangler JL models equipped with the M220 rear axle.
