GM Truck Diff Cover 12 Bolt

The Racing Power Co-Packaged GM Truck Diff Cover 12 Bolt is a direct-fit, steel differential cover engineered for General Motors 12-bolt rear axle assemblies found in full-size pickup trucks and performance vehicles. This chrome-plated cover protects the differential internals from road debris, mud, and moisture while maintaining structural rigidity under high-load conditions typical of towing, off-road recovery, and sustained payload operations.

Constructed from heavy-gauge steel with a mirror-polished chrome finish, this differential cover weighs 3.1 lbs and fits the standard 12-inch GM bolt pattern without modification. The chrome coating provides corrosion resistance in wet environments and salt-air conditions, critical for vehicles exposed to coastal roads or winter treatment. Racing Power Co-Packaged differentials covers maintain OEM sealing geometry to prevent fluid seepage while allowing proper thermal management during extended highway or hauling scenarios.

Buyers sourcing GM truck differential covers for restoration, upgrade, or replacement will find this unit compatible with classic and modern full-size GM trucks equipped with the 12-bolt differential. The chrome finish adds visual appeal for show trucks while the steel construction ensures durability in working vehicles. Installation requires only standard tools and a torque wrench set to manufacturer specifications; no drilling or modification of the axle housing is required.

This cover represents the entry-level choice for owners seeking OEM-equivalent protection without performance-oriented features like deep sumps or integrated cooling fins. For fleet maintenance, light-duty work trucks, and restorations prioritizing stock appearance, the Racing Power Co-Packaged design delivers reliable protection at a competitive price point.
