ATP Differential Cover P/N:111101
Keep the ring-and-pinion gears, bearings, and bushings bathed in lubricant with the ATP Differential Cover Kit 111102. This differential cover acts as a lid that holds gear lube in place, and it drops in as a direct-fit replacement across a wide list of GM cars and trucks — including the 1982-2002 Chevrolet Camaro, 1982-2004 Chevrolet S10, 1985-2005 Chevrolet Astro, 1991-2004 GMC Sonoma, and 1982-2002 Pontiac Firebird. See the Buyer's Guide tab for the full list of covered applications.
Differential covers can be damaged by road debris, corrosion, or over-tightened bolts and drain plugs. Once the seal is compromised, gear lube can escape — and without lubrication the differential quickly wears. If a leaking, dented, or corroded cover is the cause of your gear-oil loss, this kit replaces it and restores a clean sealing surface.
