Description

BANKS Ram-Air Rear Diff cover for 01-19 Chevy/GMC and 03-18 Ram

Banks Ram-Air Differential Cover is unlike any other. After testing covers with flat-backs and those with larger fluid capacities, it was apparent that those covers do not cool as well as advertised and suffer from poor fluid dynamics. As a result, flat-backs reduce fuel economy. Banks Ram-Air differential cover extends lubrication life and retains fuel economy!

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.

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 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.
At $3.50 per gallon of diesel, Flatback owners will spend approximately $447 in lost fuel economy over stock, enough money to buy another diff cover

Features:

  • Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle
  • New patented design features Ram-Air scoops which is engineered to break-away if snagged on an obstacle
  • Forces air up and into massive heat radiation fins providing the fastest cooling on the market
  • Cover mates perfectly with differential housing for unobstructed fluid flow
  • Low fluid aeration means longer fluid life
  • No need to remove cover to change fluid
  • Internal volume: 4 quarts matching factory fill level
