BANKS 19249 REAR RAM-AIR DIFFERENTIAL COVER KIT FOR 01-19 GM 2500HD/3500HD | 03-18 DODGE RAM 2500/3500

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.

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

The Banks 19249 Ram-Air Differential Cover Kit for Rear 2001-2019 GM 2500HD/3500HD and 2003-2018 Dodge Ram 2500/3500 sets a new standard in performance and design. With a patented Ram-Air technology that outperforms traditional differential covers, this innovative product is engineered to enhance fluid flow, reject excessive heat, and improve overall gearset longevity.

Designed by the Banks Engineering team, this differential cover is purpose-built to optimize fluid dynamics and cooling efficiency. The incorporation of Ram-Air scoops ensures fast cooling by introducing cold, high-velocity air to the differential, effectively eliminating the dead air zone behind it. The cover features heat radiation fins and advanced engineering to facilitate better heat transfer, resulting in superior cooling capabilities compared to stock covers.

One of the key advantages of the Banks Ram-Air Differential Cover is its ability to outperform flat-back high-capacity covers while using less lubricant. This leads to extended service intervals, reduced maintenance costs, and prolonged gear life. Additionally, the cover’s construction and design ensure optimal fluid flow, minimizing resistance and aeration that can degrade the gearset and reduce fuel economy.

With a focus on both performance and durability, the Banks Ram-Air Differential Cover is crafted from A380 aluminum diecast with CNC machined surfaces, ensuring a lightweight yet robust build. The kit includes stainless steel fasteners, a magnetic drain plug, and a 20-degree angled fill port for convenient access during fluid changes. The innovative design elements, combined with technical specifications and detailed features, make this differential cover a top choice for upgrading and enhancing the performance of your vehicle’s drivetrain.

Backed by a Limited Lifetime Warranty and US Patent 10,443,705 B1, the Banks 19249 Ram-Air Differential Cover Kit promises unmatched cooling efficiency, fluid dynamics, and gearset protection for your heavy-duty truck or SUV. Experience the difference that superior engineering and cutting-edge design can make in optimizing your vehicle’s performance with the Banks Ram-Air Differential Cover.
