Introducing the Banks Power Ram-Air® Diff Cover Kit

Patented design cools 5X better than flat-backs

Banks Ram-Air® differential cover extends lubrication life, retains fuel economy, and rejects heat faster than any other cover on the market.

Die-Cast Aluminum Construction

A380 aircraft aluminum die-cast for exceptional strength and precise fit.
Magnetic Fill Plug

Magnetic fill plug. 20° angle for easy fill. Simplifies oil changes.
304 Stainless Steel Hardware

Hex flanged mounting bolts.

Sight-Glass with Contrast Screen

Sight-glass with contrast screen and Viton O-ring seal.

Class-Leading Heat Rejection

25 external radiator fins offer 677.64 square inches of surface area to ensure optimal heat rejection.

Magnetic Drain Plug

Recessed magnetic drain plug. Simplifies oil changes.

Patented Ram-Air Scoops

Ram-Air system directs cool high-velocity air through radiator fins, eliminating the dead zone. Designed with breakaway scoops.

NPT Sensor Port

1/8in NPT port for transmission temp monitoring.

Radiused Ports

Radiused ports for smoother fluid flow.

Directional Fluid Guides

Axle-tube guides direct fluid to axle bearings without churn.

O-Ring Seal

Integrated No Mess Viton Seal. Dry-mount silicon high-pressure O-ring seal. No messy RTV required.

Precision Fit Machined Surface

CNC-machined surface ensures precise fit.

Internal Heat Absorption Fins

Internal absorber fins offer 120 square inches of surface area to transfer heat to external radiator fins without disrupting fluid flow.

Simple Fluid Change

No need to remove cover to change fluid.

Lubricant Raceway

Ring gear raceway provides path for fluid flow to pinion and ring gear-bearing sets.

Ram-Air System w/Breakaway Scoops

Ram-Air scoop break away point prevents damage if scoop is snagged.

Purpose Built

The Banks Engineering team’s goal was to perfect fluid flow and reject BTUs from the fluid as fast as the ring and pinion puts them in. If the fluid flow is impeded in any way, it results in resistance and aeration which reduce fuel economy and creates heat, thereby degrading the fluid and decreasing the lifespan of the gearset.

Outperform The Competition, For Less

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.

Flat-Back Fail

Extra capacity "Flat-Back" covers have worse fluid dynamics than stock. Effectively splattering oil at a wall reducing lubrication on key components and increasing wear-tear and heat.

Banks Does It Right

With the proper distance between the ring gear and raceway, oil is lifted up and around the differential. The internal fluid guides directs the flow exactly to where it's needed.

Flat-Backs Dead Air

The competition has no way of directing airflow, their covers leave a deadzone so temperatures rise faster and fall slower, meaning your oil works harder and components wear faster, costing you fuel economy.

Ram-Air Engineering

The Banks differential cover is fundamentally different from its competition because it utilizes Ram-air scoops that direct air through channeled fins, cooling the differential and internal oil temperatures.

Ground Clearance

Our patented Ram-Air scoops are designed to increase airflow over the rear differential without sacrificing ground clearance. In fact, our differential cover retains the same low point as factory and competitors.

Banks Differential Covers 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
