Banks' Ram-Air differential covers for full-size pickup trucks are proven to out-cool, extend lubrication life, and reject heat faster than any other cover on the market. The patented design cools 5x better than flat-back covers because of the competition’s failure to direct airflow. With over two years of development and testing, the Banks Engineering Team was able to uncover and solve the issue of poor airflow and flawed fluid dynamics. Proprietary Ram-Air scoops direct air through channeled fins, cooling the differential and internal oil temperatures. The superior design outperforms the competition, reducing gear wear and maintenance.

Our differential covers retain the same low point as factory and competitors so you never sacrifice ground clearance. All covers include a sensor port for transmission temp monitoring, angled easy-access fill port, magnetic drain plug to simplify oil changes, and sight glass for easy viewing. For the best performance and results, we recommend AMSOIL lubricants because of the thorough testing of their full synthetic formulas.
