Banks Ram-Air Rear Differential Cover is Patented

The Banks Ram-Air rear differential cover is patented. Of all the patents Gale has applied for, this one was approved the quickest. The examining attorney found nothing like it.


This week Gale received a nifty plaque from the United States Patent and Trademark Office displaying a summary of the patent itself. His office wall is now covered with these wonderful wood and metal documents.


Now available for 2001-2019 Chevy/GMC and 2003-2018 RAM pickups with AAM 11.5″ or 11.8″ 14-bolt rear axle. It outcools all flatbacks by 5X and offers superior fluid dynamics and aerodynamics via its exclusive Ram-Air cooling scoops. Order yours here. Ford coming soon!
