Banks Power Ram-Air Differential Cover for Ram 1500 HD Extended Lubrication

Banks Power Ram-Air® Differential Cover for Ram 1500 HD — Extended Lubrication Optimize gear life and towing confidence with the Banks Power Ram-Air® differential cover, engineered to extend lubricant life while preserving fuel economy. Its patented Ram-Air scoops deliver cold, high-velocity air to the differential, overcoming the “dead air zone” behind the housing and dramatically improving cooling performance. Patented Ram-Air design forces air into massive external fins for superior heat dissipation. Proven cooling: Banks cools up to 5× better than flat-back covers in on-road towing tests and 118% better in sustained 200 hp/60 mph tests. Efficient lubrication: Requires less fluid while extending service intervals—save money and reduce maintenance frequency. Durable, vehicle-friendly fit: Clears spare tire heat shields, Panhard bars and other components without sacrificing ground clearance. Practical sealing: Dry-mount high-pressure silicone O-ring—no messy RTV required. Safety feature: Engineered to break away if snagged on an obstacle. Warranty: Limited Lifetime Warranty for long-term peace of mind. Designed and tested against competitors, the Banks Ram-Air® cover outperforms stock and high-capacity flat-back covers while using less lubricant. Ideal for Ram 1500 HD owners who tow, haul, and demand reliable differential cooling and extended lubrication intervals.
