Banks Differential Cover 19259 Details

Banks Power Ram-Air differential covers for AAM 11.5" and 11.8" 14-Bolt Rear Axles  have been tested and proven to provide greater cooling than stock AND aftermarket competitor flat-back differential covers. Banks diff covers 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.
