The Yukon Gear & Axle polished aluminum differential cover for GM 8.6-inch, 8.2-inch and 8.5-inch rear housings replaces the factory cover with an OE-style aluminum piece finished to a mirror polish to elevate appearance. It includes 5/16 cover bolts. Finned styling increases surface area for heat dispersion while the direct-replacement design bolts on without modification for a cleaner axle presentation.
