Now at Summit Racing: B&M Differential Covers

Passively lower operating temperatures.

Tuners work hard to suppress engine and transmission heat. Cooling the differential is equally important. B&M Differential Covers feature a series of fins that serve a dual purpose. First, the fins add critical strength to the casting. Second, the fins serve as heat sinks, absorbing heat from the gear oil and dissipating it away from the differential. B&M differential covers also increase gear oil capacity, further improving cooling capability.

The covers have drain and fill plugs to make differential service easier. Better still, the drain plug has a magnetic tip to prevent any excess metal filings from getting tossed around inside the carrier. Each B&M differential cover includes hardware.

B&M has been hard at work adding more and more differential cover models for late model trucks. Notable applications include:

GM 8.5 In.
GM 8.875 In. Truck
GM 9.5 In.

Ford 9.75 In.
