Banks Power Ram-Air Black Differential Cover Kit - 11.5/11.8-14 Bolt - Select GM/RAM 2001-2019

Fits select 2001-2019 Chevrolet Silverado, GMC Sierra, and Dodge/RAM 1500, 2500, and 3500 trucks with 11.5" or 11.8" 14-bolt rear differentials.

The Banks Ram-Air differential cover is engineered to solve the cooling deficiencies of conventional flat-back aftermarket covers. While high-capacity covers often increase fluid volume, they frequently fail to manage airflow, creating a "dead air zone" behind the housing. This patented design features functional Ram-Air scoops that force high-velocity air through external heat radiation fins, resulting in cooling performance up to 5X better than flat-back designs during on-road towing tests.

Beyond external cooling, the internal geometry is precision-modeled to optimize fluid dynamics. A specialized ring gear raceway guides lubricant directly to the ring and pinion interface and out to the axle tube bearings while reducing fluid aeration. The kit simplifies maintenance with a built-in sight glass for quick level checks and a magnetic drain plug to capture metallic wear particles. Installation is streamlined with a reusable O-ring seal, eliminating the need for messy RTV silicone.
