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.

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.

The Superior Choice, Backed By 18 Months Of Testing

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.
