Fitment Alert: AAM

Does Not Fit Ram Trucks With Airbag Suspension Alone. See Fitment Note

Sway Bar Spacers (#19249-2) required on Ram Trucks with OEM sway bar.

Banks Ram-Air® Differential Cover is the best one on the market without question. Thanks to its superior fluid flow and aerodynamics, the Ram-Air® Cover out-cools stock and flat-back high-capacity covers and does so with less lubricant. Extend your gear life, use less fluid, and save money between fluid changes with Banks.

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
Technical Specs
