Banks Power Natural Aluminum Ram-Air Differential Cover Kit w/Hardware Chevrolet | GMC | Ram with AAM 11.5 Inch or 11.8 Inch 14 Bolt Rear Axle 2001-2019 - 19259
Banks Ram-Air Differential Cover is unlike any other. After testing covers with flat-backs and those with larger fluid capacities, it was apparent that those covers do not cool as well as advertised and suffer from poor fluid dynamics. As a result, flat-backs reduce fuel economy. Banks Ram-Air differential cover extends lubrication life and retains fuel economy!

When it comes to product development, we only make products that increase performance and beat the competition. So when we tested the popular Diff Covers on the market, we were shocked to find out that they actually hurt performance. This lead to the development of something so New and Incredible that our performance design has a United States Patent.

Look, when we set out to build a product for your vehicle, we only engineer the best. What else would you expect from a company with a winning legacy that spans decades. We are here to win, and we just did (AGAIN) in a huge way.

Features and Benefits:
  • Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle

  • New patented design features Ram-Air scoops
  • Forces air up and into massive heat radiation fins providing the fastest cooling on the market

  • Engineered to break-away if snagged on an obstacle
