Banks Power 19252 Ram-Air Differential Cover Kit for Ford Sterling 10.25/10.5

The Banks Power Ram-Air Differential Cover revolutionizes differential cooling with patented technology that outperforms all competitors. Unlike flat-back covers with larger fluid capacities that reduce fuel economy, the Ram-Air design cools 5X better than flat-back covers in on-road towing tests and 118% better in sustained high-speed testing.

Patented Ram-Air Cooling System:

• Ram-Air scoops provide cold high-velocity air, overcoming the "dead air zone" behind the differential and forcing air up into massive heat radiation fins
• 24 external radiator fins offer 694.2 square inches of surface area for optimal heat rejection
• Internal fins transfer heat through the cover into the external fins
• Breakaway scoops engineered to detach if snagged on obstacles

Premium Construction and Features:

• Crafted from A380 aircraft aluminum diecast for exceptional strength and precise fit
• Dry-mount high-pressure silicone O-ring seal eliminates messy RTV cleanup
• Sight-glass with contrast screen and Viton O-ring seal
• Magnetic fill plug with 20° angle for easy filling and simplified oil changes
• Recessed magnetic drain plug simplifies maintenance
• Includes chrome-plated flanged mounting bolts and 304 stainless steel hardware

Advanced Fluid Dynamics:

• Radiused ports for smoother fluid flow, axle-tube guides to direct fluid to bearings, and ring gear raceway for efficient flow control
• Superior fluid and aerodynamics outperform stock and flat-back covers with less lubricant, extending service intervals and saving money while extending gear life

The design clears spare tire heat shields, Panhard bars, and other components without sacrificing ground clearance. Fits 1985-2024 Ford Sterling Axle 12-bolt with 10.25/10.5 ring gear. Note: Does not fit Super Duty with rear sway bar, F-350 DRW, or 2023-24 High-Output models. Limited Lifetime Warranty.
