Key Features

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

FITMENT CHECK

animation comparing factory differential cover size vs Banks Ram-AirDownload and print out the fitment guide to check for clearance.

When using this guide for fitment, make sure that either (a) your truck’s full weight is on the wheels, or (b) you lifted the truck by the diff. When the truck is lifted off the ground, your swaybar (if you have one) moves and may cause a false fitment reading.
