KEY FEATURES

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

24 external radiator fins offer 694.2 extra 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.

KEY FEATURES

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.

Graphic highlighting covers machined surface

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.

HEAT RADIATION COMPARISON

The Banks Ram-Air cover features deep external fins with 160% more exterior heat radiation surface area than Mag-Hytec, or almost 5x that of the factory cover.

Bar chart comparing external heat surface area. Banks Ram-Air Cover has 160% more than a flat-back cover.

HEAT ABSORPTION COMPARISON

With 22 internal heat absorption fins to pull heat, total internal surface area is almost doubled vs stock providing a total of 222.2in².

THE SUPERIOR CHOICE, BACKED BY 18 MONTHS OF TESTING

What began with a simple question, resulted in millions of video views, innovation, and another patented Banks product.

All other manufacturers simply copied previous designs. They all run on the belief that "more oil means cooler temps."

The Banks Engineering Team uncovered two underlying problems with aftermarket covers; poor air flow and flawed fluid dynamics. The Banks Ram-Air® differential cover solves both issues.

KEEPS YOUR DIFF COOL

And your oil even cooler

Tests were performed on a stretch of California’s infamous Grapevine (Interstate 5) on the same truck, with the same driver and the same load, at the same time of day and same temperature

After testing covers with flat-backs and those with larger fluid capacities, it was apparent that these covers do not cool as well as advertised, suffer from poor fluid dynamics, and they all make no use of airflow to cool actively.

BANKS RECOMMENDS AMSOIL LUBRICANT

We searched for information on every popular brand of gear oil. The only company with in-depth knowledge and the willingness to share it was AMSOIL.

They are every bit as thorough in their development as we are. The more info we discovered, the more we liked how AMSOIL designs and test their products. If you want to see for yourself, here is a link to their 75w90 test results.

MAINTAINS OE FILL LEVEL

We decided to stick with the manufacturer's suggested viscosity and use AMSOIL Severe Gear Synthetic Extreme Pressure Gear Lube. Fill level remains at the recommended levels as factory.

Check owners manual for recommended fill level for your specific vehicle.

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.
