Product Details
Dodge Ram 2007, Ram-Air™ Differential Cover Kit by Banks®. 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.
Specifications

Features
- Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle
- Banks cools 118% better than flat-back covers in controlled 200hp 60mph sustained dyno tests
- New patented design features Ram-Air scoops
- Forces air up and into massive heat radiation fins providing the fastest cooling on the market
- Provides cold high velocity air, overcoming "dead air zone" behind differential
- Engineered to break-away if snagged on an obstacle
- Internal heat absorption fins transfer heat through the cover to the external fins
- Dry-mount high-pressure silicone O-ring seal. No messy RTV clean up when servicing differential
- Clears spare tire heat shield, Panhard bars and other suspension components
- Lowest point is the rear differential housing, not the Banks Ram-Air cover
- Limited Lifetime Warranty
The All-New Patented Banks Ram-Air Differential Cover WIPES OUT THE COMPETITION!
When it comes to product development, Banks only make products that increase performance and beat the competition. So when Banks tested the popular Diff Covers on the market, Banks were shocked to find out that they actually hurt performance. This lead to the development of something so New and Incredible that this performance design has a United States Patent. Look, when Banks set out to build a product for your vehicle, Banks only engineer the best. What else would you expect from a company with a winning legacy that spans decades. Banks are here to win, and Banks just did (AGAIN) in a huge way.
Purpose Built
The Banks Engineering team’s goal was to perfect fluid flow and reject BTUs from the fluid as fast 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.
Anemometer: Air Velocity
After affixing anemometers fore and aft of the rear differential, a dead zone was discovered. Like the wing of plane, the rear differential splits the air. At a road speed of 70 mph, air speed was measured at 32 MPH in front of the differential and 11 MPH 20” behind the differential. This indicated an area of dead air. This low velocity dead zone extends as far out as 36” from the back face of the cover. No matter how deep the cooling fins are, they’re unable to adequately reject heat due to inadequate airflow over the surface of the fins. This discovery resulted in the Ram-Air scoop concept. As the truck moves through the air, cool static air is forced into the Ram-Air scoops and directed 90° up and through the long, thin heat radiation fins.
Heat Absorption and Radiation — Surface Area Comparison
The Banks Ram-Air cover features 169% more exterior heat radiation surface area and 21% more internal heat absorption surface area than Mag-Hytec. This is impressive considering the Banks cover retains the stock 4-quart fluid capacity.
Fuel Economy Testing — Simulated City Driving
Fuel Economy was tested on the Mustang dyno using the OBD-II fuel flow rate and vehicle speed data, as well as the Banks emissions analyzer to measure fuel economy calculated from tailpipe emissions. The dyno was calibrated to simulate a 7,500 lb vehicle with an engine output of 30 HP required to maintain a 50 mph steady state speed. The truck was warmed to operating temperature then held at a constant 50 mph for a fixed length of time to procure an accurate average fuel consumption. The test was repeated for all covers as per their respective manufacturer’s fill level specifications.
