The Yukon Hardcore differential cover for GM 14-bolt rear housings (early) is made from thick-walled nodular iron to protect internal locker, gear and axle components. It increases housing rigidity, features contoured inner surfaces to accelerate oil circulation for cooling, and ships with high-strength cover bolts and a black powder-coat finish. Explicitly fits GM 14-bolt rear applications using 3/8 in. bolts.
