The original differential side cover is made of cast aluminum. Under load there can be a tremendous force applied to this cover, and it can break, sometimes resulting in a damaged ring and pinion-or worse.
Upgrading to a billet side plate will add strength and increased reliability to the differential section.
Our cover features an oil passageway for the differential bearing and accepts the standard taper bearing, radial seal and O-ring. The turbo version further incorporates a thrust screw to reduce ring gear deflection under load.
