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
Technical Specs
- Weight: 11.7 lbs
- External heat radiation fin count: 23
- Internal heat absorption fin count: 22
- Dimensions: 13.3 in X 12.8 in X 3.5 in
- External heat radiation fin surface area: 694.2 in2
- Internal heat absorption fin surface area: 103.1 in2
- External heat radiation total surface area: 741.9 in2
- Internal heat absorption total surface area: 222.2 in2
- Fasteners: 12 x stainless steel 5/16 flange hex bolts
- Material: A380 aluminum diecast with CNC machined surfaces
- Internal Volume: About 3.3-3.6 Qts (Check OEM Owners Manual)
Oil Service
- 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)
