B&M Differential Covers

B&M differential covers are strong and cool! Cast and machined from premium aluminum alloy, they feature heavy-duty structural cooling fins, a larger fluid capacity, and high-strength magnetic drain plugs that aid in catching ferrous metal particles. B&M differential covers add some strength with extra cooling ability to your rear end.
