Yukon Hardcore nodular iron differential cover for GM 8.5in rear housings is designed to protect gears, lockers and axles from off‑road impacts while increasing housing rigidity. The contoured inner surfaces promote faster oil circulation for cooling, and the thick‑walled construction resists deflection under high torque. Finished in black powder coat with stainless accent plate and high‑strength bolts, it fits standard and reverse rotation diffs.
