10 BOLT REAR ALUMINUM DIFFERENTIAL COVER (8.5")

This stock replacement machined cast aluminum rear end cover. It measures about 4″ deep. This will clear the factory crossflow muffler. It allows the rear end to hold more fluid and the fin design aids in cooling.Cover is made from machined 319 aluminum, and comes complete with a drain plug and O-ring, a cover gasket, and hardware.

An excellent upgrade for a stock rear end.
