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.

Best dif cover on the market!!
5
I ran a flat back for years and towing a 35 foot camper to lake Powell in July and would get that dif temp to well over 250°. My 14' tool trailer would get it well over 200°. I've now had this Banks cover on for a couple weeks and it refuses to get over 180° - 190° with a full tow. This cover is even far better than OEM. Mr Gale Banks never fails to produce anything but perfection. Order # 2101634

I haul a heavy camper around two times a month and it is good insurance that the rear end stays cool. This product will do that, very pleased. Thank You Banks for such a great product!
