Banks Power Ram-Air Differential Cover for Extended Lubrication Life

Banks Power Ram-Air Differential Cover — Extended Lubrication Life Extend gear life, reduce service intervals, and retain fuel economy with the patented Banks Power Ram-Air differential cover. Engineered for superior fluid dynamics and cooling, this cover out-performs stock and flat-back high-capacity designs while using less lubricant. Why choose the Ram-Air Cover? Patented Ram-Air scoops deliver cold, high-velocity air to eliminate the dead-air zone behind the differential. Massive external fins and internal heat-transfer fins move heat from internal fluid to the exterior for rapid dissipation. Proven performance: Cools up to 5× better than flat-back covers in on-road towing tests and 118% better in sustained 200hp/60mph tests. Efficient lubrication: Requires less fluid while increasing distance between service intervals—saving money and extending gear life. Durable and vehicle-friendly: Clears spare tire heat shields, Panhard bars and other components without reducing ground clearance; engineered to break away if snagged. Clean, secure seal: Dry-mount high-pressure silicone O-ring—no messy RTV required. Limited Lifetime Warranty for long-term peace of mind. The Banks Power Ram-Air Differential Cover is the result of decades of performance engineering. If you expect the best for your drivetrain—better cooling, longer lubrication life, and uncompromised vehicle fitment—this patented design delivers.
