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.
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.
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
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.
