Banks Ram-Air Differential Covers
Banks Ram-Air Differential Covers are engineered to improve rear-axle cooling while providing a durable, high-strength replacement for the factory differential cover. The patented Ram-Air design uses external cooling fins and directed airflow to help manage differential fluid temperatures under demanding conditions.
Ram-Air Cooling
Unlike conventional flat-back differential covers, the Banks Ram-Air design incorporates aerodynamic features that direct air across the cover while the vehicle is moving. Large external fins increase surface area to help transfer heat away from the differential fluid.
Proper Fluid Dynamics
The internal geometry of the Banks differential cover is designed to work with the rotating ring gear rather than simply increasing fluid capacity. This helps maintain proper lubrication and fluid circulation inside the differential while reducing unnecessary resistance.
Heavy-Duty Construction
Banks Ram-Air Differential Covers are built for demanding truck applications including towing, hauling, off-road use, and other conditions that place increased thermal load on the rear axle. The rigid construction also provides a substantial upgrade over many factory stamped-steel covers.
Multiple Rear Axle Applications
Banks offers Ram-Air Differential Cover Kits for several popular heavy-duty rear axles used in Ford, Chevrolet, GMC, Dodge, and Ram trucks, including Sterling, AAM, and Dana applications.
