The ultimate in rear axle cooling and overall function, this rear axle cover is the ONLY scientifically proven performance rear diff cover on the market. If there's one thing Gale Banks does well, its his R&D. Flat back high capacity covers don't stand a chance!
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, they reduce fuel economy. Banks Ram-Air differential cover increases fuel economy and extends lubrication life!
