Banks Power Ram-Air® Differential Cover for Extended Lubrication Life

Banks Power Ram-Air® Differential Cover — Extended Lubrication Life Increase gear life, reduce service intervals, and retain fuel economy with the Banks Power Ram-Air® Differential Cover. Engineered and patented to deliver superior cooling and fluid dynamics, this cover outperforms stock and flat-back high-capacity covers while using less lubricant. Key Benefits Patented Ram-Air scoops deliver cold, high-velocity air to eliminate the “dead air zone” behind the differential. Massive external fins dissipate heat efficiently while internal fins transfer heat from the fluid to the housing. Proven cooling performance: Banks cools up to 5× better in on-road towing tests and 118% better in sustained 200 hp/60 mph tests versus flat-back covers. Extended lubrication life and increased service intervals means lower maintenance cost and longer gear life. Dry-mount high-pressure silicone O-ring — no messy RTV required. Engineered break-away design for protection if snagged on obstacles; clears spare tire heat shields, Panhard bars, and other components without losing ground clearance. Limited lifetime warranty for lasting peace of mind. Why Choose Banks Power Banks Power applies decades of performance engineering to real-world problems. When competitive diff covers negatively impacted performance, we redesigned the solution from the ground up — earning a U.S. patent in the process. The Ram-Air® Differential Cover is built to win: better cooling, less fluid, longer life, and proven results.
