It's a direct replacement for a leaking, damaged, or missing cover gasket, providing a reliable fiber seal between the differential cover and axle housing sealing rail during cover reinstallation, fluid changes, or cover upgrades.\u003c\/p\u003e\n\u003cp\u003eGM used two different 12-bolt differential cover designs on 8.875\" axles — a \"car style\" and a \"truck style\" — and the two are not interchangeable. This gasket is cut for the truck-style cover, commonly found on Chevrolet C10\/K10 and Silverado trucks. If your application is a Camaro, Chevelle, or Nova, TSP's \"car style\" 12-bolt gasket (SKU SP4930) is the correct part instead.\u003c\/p\u003e\n\u003cp\u003eThis gasket is sold individually and includes no cover, hardware, or drain plug.
