The All-New Patented Banks Ram-Air Differential Cover WIPES OUT THE COMPETITION!
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.

This Banks Ram-Air differential cover is constructed of aircraft-grade aluminum and is intended to be painted or powder-coated. If left uncoated, discoloration and/or surface oxidation can be expected. Discoloration or surface oxidation is not covered under its limited lifetime warranty.

Banks Ram-Air differential cover extends lubrication life and retains fuel economy.
