Does Not Fit F-350 DRW
Does Not Fit 2023-24 High-Output
Banks Ram-Air® differential cover extends lubrication life and retains fuel economy. 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.
Key Features
- New patented design features Ram-Air scoops for fastest cooling
- Provides cold high velocity air, overcoming “dead air zone” behind differential
- Scoops force air up and into massive heat radiation fins
- Engineered to break-away if snagged on an obstacle
- Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle
- Cools 118% better than flat-backs in 200hp 60mph sustained tests
- Dry-mount high-pressure silicone O-ring seal. No messy RTV clean!
- Internal fins transfer heat through the cover into the external fins
- Clears spare tire heat shield, Panhard bars and other components
- Does not sacrifice any ground clearance
- Limited Lifetime Warranty
- Axle tube lubricant guides directs lube to bearings w/o overfilling
- Cover mates flush with differential housing for smooth fluid flow
- Ring gear raceway controls fluid flow to the pinion and bearings
- Low fluid aeration means longer fluid life
- Weight: 11.8 lbs
- External heat radiation fin count: 23
- Internal heat absorption fin count: 24
- Dimensions: 13.7 in X 13.5 in X 3.4 in
- Fasteners: 14 x stainless steel M10 flange hex bolts
- Material: A380 aluminum diecast with CNC machined surfaces
- Magnetic drain plug
- Magnetic fill port plug
- Angled fill port for easy access
- No need to remove cover to change fluid
- 1/2 in sight glass with contrast screen (visual aid) and Viton seal
- Banks recommends Amsoil 75W-140 Severe Gear Synthetic Gear Lube
- Fill level depends on model year: (About 3.61 Qts Fill To OEM Level)
Specifications
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
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 lowpoint as factory and competitors.
Why It's Better
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
Magnetic Fill Plug
304 Stainless Steel Hardware
Sight-Glass with Contrast Screen
Class-Leading Heat Rejection
Magnetic Drain Plug
Patented Ram-Air Scoops

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
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
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.
Fitment Check
Download and print out the fitment guide to check for clearance. When using this guide for fitment, make sure that either (a) your truck's full weight is on the wheels, or (b) you lifted the truck by the diff. When the truck is lifted off the ground, your swaybar (if you have one) moves and may cause a false fitment reading.
