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.
Introducing the Banks Power Ram-Air Diff Cover Kit
Patented design cools 5X better than flat-backs
Banks Ram-Air differential cover extends lubrication life, retains fuel economy, and rejects heat faster than any other cover on the market.
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
