Banks Ram-Air Diff Cover Chevrolet Silverado/Sierra 2020-Current & Ram 2019-Current

Keep your differential running cooler under heavy loads with the Banks Ram-Air Differential Cover Kit. Engineered for Chevrolet Silverado, GMC Sierra and Ram heavy-duty trucks, this innovative cover uses Banks' patented Ram-Air® cooling technology to direct airflow through external cooling fins, reducing differential temperatures and helping extend gear oil life.

Unlike conventional high-capacity covers, the Banks design improves both airflow and internal oil movement to maximise cooling without increasing fluid capacity unnecessarily. The heavy-duty A380 cast aluminium construction delivers exceptional strength while retaining factory ground clearance for everyday driving, towing and off-road use.

Maintenance is also easier thanks to the integrated sight glass, magnetic drain plug, angled fill port and built-in temperature sensor port. A durable Black Ops powder-coated finish completes one of the most advanced differential covers available for modern heavy-duty trucks.
