Differential Cover Kit Satin Black/Machined, w/Hardware

19249
Cools 5X Better than flat-backs, Patented
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!
US Patent #10,443,705
Does not fit 2019 Ram
Sway Bar Spacers (#19249-2) required on 2014+ Ram Trucks with OEM sway bar.

Description

The All-New Patented Banks Ram-Air Differential Cover WIPES OUT THE COMPETITION!
When it comes to product development, we only make products that increase performance and beat the competition. So when we tested the popular Diff Covers on the market, we were shocked to find out that they actually hurt performance. This lead to the development of something so New and Incredible that our performance design has a United States Patent. 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.

Road Test: Heat Rejection — Grapevine Trailer Test
Road 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 at same temperature. Starting with a nominal 78° ambient temperature, the operator pulled an 11,650 lb weight trailer with a 2018 Chevy Silverado 2500HD 6.6L diesel. Gross combined weight was 19,750 lbs. The rear differential was heated by maintaining a constant speed of 55 mph up a 6% grade for 5 miles, ascending over 1,600’.

At the top of the 550 second hill climb, running the 3.9 quart stock differential cover, the lubricant temp was 205°. Filled with 7.5 quarts, the Mag-Hytec recorded 199° while the Banks filled with 4 quarts recorded 192.5°. Even with less lubricant, the Ram-Air cover controlled heat 2X better than the flat-back during the high horsepower hill climb!

From the crest to the end of the test, running 55 mph for 700 second at relatively constant elevation, the stock cover cooled from 205° to 195°. The Mag-Hytec cooled to 192.5° and 178.5° for Banks, a 5X improvement over the Mag-Hytec and by extension all other flat-back copies.
