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.
Sway Bar Spacers 19249-2 are required on Ram Trucks with OEM sway bar.
- 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% 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

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.
Banks Ram-Air differential cover extends lubrication life, retains fuel economy, and rejects heat faster than any other cover on the market.
The Banks Ram-Air cover features deep external fins with 169% more exterior heat radiation surface area than Mag-Hytec, or over 4.5x that of the factory cover.
The 26 internal heat absorption fins add an extra 120in2 to pull heat, or almost 70% more area than stock.
Our patented Ram-Air scoops are designed to increase airflow over the rear differential without sacrificing ground clearance. In fact, our differential cover retains the same low point as factory and competitors.
