BANKS Differential Cover KIts

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.

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

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

Magnetic Drain Plug

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.

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.

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.

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.

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.

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.

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.
