Product Description

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!

The new Banks diff cover cools 5 times better than flat-back diff covers in on-road towing tests over the same road with the same weather, driver and vehicle. It cools 118% better than flat-back covers in controlled 200hp 60mph sustained dyno tests. The new patented design features Ram-Air scoops. These force air up and into massive heat radiation fins providing the fastest cooling on the market. The high velocity air overcomes the “dead air zone” behind your differential. And, the fins are engineered to break-away if they are snagged on an obstacle.

The Banks Diff Cover is die-cast from A380 aircraft aluminum for exceptional strength and a precise fit. The installation kit comes 12-point chrome-plated flanged mounting bolts. 24 external radiator fins offer 534 square inches of surface area to ensure optimal heat rejection, giving class-leading heat rejection. Patented Ram-Air Scoops direct cool high-velocity air through radiator fins, eliminating the dead zone. A handy half inch stainless steel sight-glass with contrast screen and Viton O-ring seal, together with a recessed magnetic 3/8" drain plug with 3/8" square drive make oil changes a snap.
