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.
Does NOT fit 2019+ Ram 6.7L Diesel.

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
 
- 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
 
- Weight: 11.7 lbs
 - External heat radiation fin count: 24
 - Internal heat absorption fin count: 26
 - Dimensions: 14.2 in X 13.3 in X 3.8 in
 - External heat radiation fin surface area: 533.782 in2
 - Internal heat absorption fin surface area: 119.882 in2
 - External heat radiation total surface area: 808.81 in2
 - Internal heat absorption total surface area: 215.78 in2
 - Fasteners: 14 x stainless steel M8-1.25 flange hex bolts
 - Material: A380 aluminum diecast with CNC machined surfaces
 - Internal Volume: About 4.0 Qts (Check OEM Owners Manual)
 
- Magnetic drain plug
 - Magnetic fill port plug
 - 20° angled fill port for easy access
 - No need to remove cover to change fluid
 - 1/2 in sight glass with contrast screen (visual aid) and Viton seal
 - Banks recommends Amsoil 75W-90 Severe Gear Synthetic Gear Lube
 - Fill level depends on model year: (About 4.0Qts Fill To OEM Level)
