Specs At A Glance

Good To Know

Q: Does this cover include a gasket or bolts? A: No hardware is confirmed with this listing, so plan to source a gasket and cover bolts separately. Clean both mating surfaces and torque the bolts to spec for a leak-free seal.

Q: Will this cover change my fluid fill amount? A: A deeper aluminum cover typically increases fluid capacity, so fill to the level specified for your axle rather than the stock amount. Check the level after the first few drives.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
