Banks Power Ram-Air Differential Cover Kit Satin Black/Machined w/Hardware for 17+ Ford F250 HD Tow Pkg and F350 SRW with Dana M275 Rear Axle - 19280

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

Ground Clearance

Our patented Ram-Air scoops are designed to increase airflow over the rear differential without sacrificing ground clearance. In fact, our differential cover retains the same lowpoint as factory and competitors.

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.

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

• 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
