GM Truck Diff Cover 12 Bolt

The Racing Power Co-Packaged GM Truck Diff Cover 12 Bolt is engineered for owners and mechanics who demand reliable differential protection on their General Motors trucks. If you've upgraded suspension, increased payload capacity, or plan aggressive towing, a quality differential cover is essential—it shields your ring-and-pinion assembly from road debris, moisture, and thermal stress while maintaining proper lubrication circulation.

This replacement cover fits the factory 12-bolt differential found in countless GM pickup platforms, making it an essential upgrade for both restoration builds and heavy-duty work trucks. Racing Power's design focuses on durability and straightforward installation—the cover bolts directly to your existing differential housing without modification. The cast construction provides superior heat dissipation, which is critical when you're running synthetic gear oil or operating in high-load conditions.

This cover is ideal for truck owners performing regular maintenance, off-road enthusiasts, and shops specializing in GM vehicle service and modification. Whether you're replacing a corroded factory cover or upgrading as part of a differential refresh, this Racing Power product ensures a perfect fit and proper sealing gasket contact.
