Banks Power 19288 Ram-Air Differential Cover for AAM 11.5/12 14-Bolt Rear Axle

The Banks Ram-Air differential cover extends lubrication life, retains fuel economy, and rejects heat faster than any other cover on the market. Manufactured using aircraft grade diecast A380 aluminum for unbeatable strength, this patented design represents a breakthrough in differential cooling technology for heavy-duty trucks.

Patented Ram-Air Cooling Technology:

The patented design forces air up and into massive heat radiation fins providing the fastest cooling on the market and creates cold high velocity air overcoming "dead air zone" behind the differential cover. Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle, and cools 118% better than flat-backs in 200hp 60mph sustained tests. The 25 external radiator fins offer 677.64 square inches of surface area to ensure optimal heat rejection.

Key Features:

• Internal heat absorption fins transfer heat through the cover to the external fins
• Magnetic 3/8" drain plug, 20 degree magnetic 3/4" fill port plug, and a 1/2" stainless steel sight glass with contrast screen and viton seal
• Silicone O-ring seal with high-pressure seal that does not require the use of RTV
• Unique fin design is engineered to break away if it becomes snagged on an obstacle
• 1/8in NPT port for transmission temp monitoring
• 304 stainless steel hex flanged mounting bolts and sight-glass with contrast screen and Viton O-ring seal
• Does not sacrifice any ground clearance

Superior Fluid Dynamics:

This cover utilizes internal guides to direct the gear lube to bearings without overfilling as this cover mounts flush with differential housing for improved fluid flow. This smooth transmission reduces fluid aeration for longer lube life while the inner cooling fins transfer heat through the cover into the outer fins.

Important Notes:

• Does NOT fit Ram trucks with factory airbag suspension alone
• Sway Bar Spacers (#19249-2) required on Ram trucks with OEM rear sway bar
• Internal volume holds approximately 4.4 quarts

This complete kit includes all necessary hardware for installation and is backed by a limited lifetime warranty. 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.
