Description
Banks started from scratch while sparing no expense in the creation of the Banks Power AAM 11.5" 14-Bolt Rear Ram-Air Differential Cover. Banks set out in search of the answer to the age old "Do rear differential covers provide any real benefit or are they just bling?" After many, many hours of research, Gale and the Banks Engineering Team uncovered two underlying problems with the aftermarket differential covers on the market; poor air flow as well as flawed fluid dynamics. Both issues are not a concern with the Banks Ram-Air Differential Cover.
After performing tests on covers with a flat-back design and larger fluid capacities, Banks found that the hard angle of the flat-back causes poor fluid dynamics. With computer-aided designing and road-testing, the Banks Ram-Air differential cover has improved fluid dynamics to help increase fuel economy and extend lubrication life. It also cools 118% better than its flat-back competitor at sustained 60mph dyno tests and 4X better in on-road towing tests!
The Banks Ram-Air Differential Cover is constructed from A380 aluminum diecast featuring internal and external cooling fins, patented Ram-Air scoops to flow air around the cooling fins, dry-mount silicone O-ring seal, and includes chrome-plated mounting hardware. There's also no need to remove the cover to service the oil. Banks includes a magnetic drain plug, magnetic fill plug which is at a 20° angle for easier filling. A 1/2" stainless steel sight glass gives you the ability to monitor your fluid level and condition.

Very high quality machine work, fit, & finish. Definitely a good heat sync and the fluid level sight glass is a great feature. I still do not understand the point of the drain plug on the Banks cover when the AAM 11.5" axle already has a 3/8" drive magnetic drain plug on the very bottom of the housing which is at a lower fluid level than the one made into the Banks cover. 4 out of 5 starts for redundant drain plug.

Easy to install. The o ring type gasket was a little long but I was able to massage it into the groove.
It's nice being able to see the level and condition of the fluid.
Overall I feel it was worth the cost.
