Why It's Better
When it comes to product development, we only make products that increase performance and beat the competition. So when
we tested the popular Diff Covers on the market, we were shocked to find out that they actually hurt performance. This
lead to the development of something so new and incredible that our performance design has a United States Patent.
Look, when we set out to build a product for your vehicle, we only engineer the best. What else would you expect
from a company with a winning legacy that spans decades. We are here to win, and we just did (AGAIN) in a huge way
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
Fill Plug
304 Stainless Steel Hardware
Sight-Glass with Contrast Screen
Class-Leading Heat Rejection
Magnetic Drain Plug
Patented Ram-Air Scoops
NPT Sensor Port
Key Features
Radiused Ports
Directional Fluid Guides
O-Ring Seal
Precision Fit Machined Surface
Internal Heat Absorption Fins
Simple Fluid Change
Lubricant Raceway
Ram-Air System w/Breakaway Scoops
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
Forced Air Cooling
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 169% more exterior heat radiation surface area than Mag-Hytec, or over 4.5x that of the factory cover.
Heat Absorption Comparison
The 26 internal heat absorption fins add an extra 120in2 to pull heat, or almost 70% more area than stock.
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
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.

"I purchased the Banks differential cover as part of my preventative maintenance plan. I was particularly impressed with the engineering and R&D behind the product, especially the enhancements designed to improve gear oil flow and cooling efficiency. I’ve since replaced the factory cover on my 2025 GMC 2500HD with the Banks unit and am very pleased with the upgrade"
Good quality; clean install; drain-fill-level big improvement
"Put the rear diff cover on my 2007 2500 with 11. 50 rear end. I was impressed with the stock cover; my truck had the good double seal gasket from the factory (no silicone). The Banks uses a serpentine o-ring that seems very reliable. The Banks mounting bolts take a lot less torque than factory specs (~12 ft-lb vs. ~30). I used a beam-type torque wrench as I find them more reliable at low torques. Although the Banks instructions say not to rely on the sight glass for level, I lined up a steel straightedge across the lower edge of two opposing mounting holes and found the center of the sight glass was just a smidge below the lower edge of the stock fill hole. . . exactly where the factory manual specifies the oil level. So using the sight glass for an occasional level check is reasonable. . . you do have to be aware that dirty oil could clog the sight glass weep holes and trap oil that mimics a correct oil level (when you might actually be low). Regardless, the cover is a good product, likely improves oil flow within the differential, and gets compliments from mechanics that work on the truck (recent diff pinion seal replacement as well as the usual general service)."

"First and foremost the packaging of the product is perfect. No rush or potential for damage. The step by step directions are highly detailed and accurate. The additional cometary on site glass usage vs. fill quantity is also helpful. As for the product , very high quality product. The casting and machining work is perfectly done. The O-ring style seal provides a 100% sealing without worry. The design of both internal cooling fins to extract heat from direct contact to the external fins with cooling Venturi style directional air flow is genius. Thank you Banks for not only putting in the time to engineer an outstanding product - but also keeping it American made. Regards Bob B Lock Haven PA."

My cover kit.
"To be honest, I haven't noticed anything different. I've also installed the Banks Elbow and the Cold Air intake. I've got 3 license plate holders now. What I wanted was a sticker to put in my back window."
Great addition
"I purchased the Banks differential cover as part of my preventative maintenance plan. I was particularly impressed with the engineering and R&D behind the product, especially the enhancements designed to improve gear oil flow and cooling efficiency. I’ve since replaced the factory cover on my 2025 GMC 2500HD with the Banks unit and am very pleased with the upgrade"
Good quality; clean install; drain-fill-level big improvement
"Put the rear diff cover on my 2007 2500 with 11. 50 rear end. I was impressed with the stock cover; my truck had the good double seal gasket from the factory (no silicone). The Banks uses a serpentine o-ring that seems very reliable. The Banks mounting bolts take a lot less torque than factory specs (~12 ft-lb vs. ~30). I used a beam-type torque wrench as I find them more reliable at low torques. Although the Banks instructions say not to rely on the sight glass for level, I lined up a steel straightedge across the lower edge of two opposing mounting holes and found the center of the sight glass was just a smidge below the lower edge of the stock fill hole. . . exactly where the factory manual specifies the oil level. So using the sight glass for an occasional level check is reasonable. . . you do have to be aware that dirty oil could clog the sight glass weep holes and trap oil that mimics a correct oil level (when you might actually be low). Regardless, the cover is a good product, likely improves oil flow within the differential, and gets compliments from mechanics that work on the truck (recent diff pinion seal replacement as well as the usual general service)."

"Very high quality billet aluminum. Easy install but will want to drop the spare tire to give yourself room to work. I’m sure this will add at least 50 HP!"
Bachman, rear differential cover - 2012 Ram 3500 dually.
"First and foremost the packaging of the product is perfect. No rush or potential for damage. The step by step directions are highly detailed and accurate. The additional cometary on site glass usage vs. fill quantity is also helpful. As for the product , very high quality product. The casting and machining work is perfectly done. The O-ring style seal provides a 100% sealing without worry. The design of both internal cooling fins to extract heat from direct contact to the external fins with cooling Venturi style directional air flow is genius. Thank you Banks for not only putting in the time to engineer an outstanding product - but also keeping it American made. Regards Bob B Lock Haven PA."

Ram 2500 rear differential cover.
"Very well engineered and designed and perfect fit! I've only used Amsoil in this truck since it was new and the rear differential has never been over 200 degree F. With a slide in camper and a 20 foot trailer at 7,000 LBS. In summer heat at Colorado altitude climbing passes over 12,000 feet. This will only complement the Amsoil protection I already have. f towing"
