BANKS 19259 DIFFERENTIAL COVER KIT (NATURAL) 11.5/11.8-14 BOLT 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

Key Highlights

• New patented design features Ram-Air scoops for fastest cooling
• Provides cold high velocity air, overcoming dead air zone behind differential
• Scoops force air up and into massive heat radiation fins
• Engineered to break-away if snagged on an obstacle
• Banks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicle
• Cools 118 percent better than flat-backs in 200hp 60mph sustained tests
• Dry-mount high-pressure silicone O-ring seal. No messy RTV clean!
• Internal fins transfer heat through the cover into the external fins
• Clears spare tire heat shield, Panhard bars and other components
• Does not sacrifice any ground clearance
• Limited Lifetime Warranty

Fluid Dynamics

• Axle tube lubricant guides directs lube to bearings w/o overfilling
• Cover mates flush with differential housing for smooth fluid flow
• Ring gear raceway controls fluid flow to the pinion and bearings
• Low fluid aeration means longer fluid life

The BANKS 19259 Differential Cover Kit in Natural finish is a top-of-the-line product designed specifically for GM and Dodge Ram trucks from 2001 to 2018. Elevate your vehicle's performance with Banks Ram-Air® technology that not only extends lubrication life but also helps retain fuel economy. This differential cover outperforms stock and flat-back high-capacity covers with its superior fluid dynamics and aerodynamics.

Featuring a 1/8in NPT sensor port for transmission temp monitoring, this cover is equipped with patented Ram-Air scoops for faster cooling, providing an impressive 5X better cooling performance in on-road towing tests compared to flat-back covers. The scoops force cold, high-velocity air to overcome the "dead air zone" behind the differential while efficiently transferring heat through internal and external fins.

With a durable design engineered to break away if snagged on obstacles, this cover ensures optimal performance without sacrificing ground clearance. The innovative fluid dynamics of the cover direct lubricant to bearings without overfilling and promote smooth fluid flow for extended fluid life. The kit includes a magnetic drain plug, magnetic fill port plug, and a 20° angled fill port for easy fluid changes without the need to remove the cover.

Crafted from A380 aluminum diecast with CNC machined surfaces, this differential cover is built to last and comes with a Limited Lifetime Warranty for peace of mind. Ensure your truck's differential is operating at its best with the BANKS 19259 Differential Cover Kit, recommended to be used with Amsoil 75W-90 Severe Gear Synthetic Gear Lube for optimal performance. Experience superior cooling, efficiency, and longevity with this exceptional differential cover kit.
