Banks Power AAM 11.50/11.80-Inch Ram-Air Differential Cover; Natural (07-19 Silverado 2500 HD)Find parts that fit my vehicle

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
