Banks Power 01-18 GM / RAM Natural Differential Cover Kit 11.5/11.8-14 Bolt

19259

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 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% 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
