Ram-Air Differential Cover Kit, Black Ops, w/Hardware 01-19 Chevy/GMC 03-24 Ram with AAM 11.5 Inch or 11.8 Inch 14 Bolt Rear Axle - Banks Power - 19269

Banks Ram-Air differential cover extends lubrication life and retains fuel economy. Thanks to its superior fluid and aerodynamics, the Ram-Air Cover out-performs stock and flat-back high-capacity covers and does so with less lubricant. Increased distance between service intervals and less lubricant means you'll save money while extending gear life.  

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

Key Highlights


New patented design features Ram-Air scoops for fastest cooling

Provides cold high velocity air, overcoming dead air zone behind differential

Scoops force air up and into massive heat radiation fins

Engineered to break-away if snagged on an obstacle

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

Cools 118 percent better than flat-backs in 200hp 60mph sustained tests

Dry-mount high-pressure silicone O-ring seal. No messy RTV clean!

Internal fins transfer heat through the cover into the external fins

Clears spare tire heat shield, Panhard bars and other components

Does not sacrifice any ground clearance

Limited Lifetime Warranty


Fluid Dynamics


Axle tube lubricant guides directs lube to bearings w/o overfilling

Cover mates flush with differential housing for smooth fluid flow

Ring gear raceway controls fluid flow to the pinion and bearings

Low fluid aeration means longer fluid life
