Differential Cover GM 8 .5in & 8.6in 10 Bolt

The Differential Cover GM 8.5in & 8.6in 10 Bolt by Specialty Products Company is a heavy-duty aftermarket upgrade designed for Chevrolet and GMC truck owners seeking reliable differential protection and enhanced cooling performance. This cover is ideal for those who frequently haul loads, tow, or want to upgrade from the factory stamped-steel cover.

Engineered specifically for GM 10-bolt differentials in the 8.5-inch and 8.6-inch configurations, this cover features a cast-aluminum construction that significantly outperforms stock stamped steel in both structural rigidity and heat dissipation. The rib-reinforced design promotes better airflow around the differential housing, helping to keep fluid temperatures lower during sustained loads or highway driving.

This differential cover is perfect for truck enthusiasts running stock or lightly modified powertrains who want to extend differential service life and improve reliability during towing or spirited driving. It is designed to fit without extensive modifications, making it a straightforward upgrade for those looking to enhance their vehicle's performance.
