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.

Key Features

• 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
