Differential Cover For 2015-2026 F150 Ford 8.8″ 12 Bolts Rear Axle | SPELAB
Function
Precision-engineered for Ford 8.8″ 12-bolt housing
Durable construction for enhanced protection
Improved sealing surface to help prevent leaks
Designed to maintain proper clearance with factory components
Ideal replacement or upgrade over factory differential cover
Innovative points:
• The external heat sink design increases the contact area between the differential cover and the surrounding air, enhancing heat dissipation performance.
• The internal diversion groove design aligns with the direction of liquid flow in the differential gear's rotation, ensuring maximum flow rate for better lubrication.
• The use of aluminum alloy material significantly improves cooling performance compared to the commonly used iron material. When comparing billet to cast products, billet items are often considered more durable and built for long-lasting performance.
• An external observation mirror with a floating ball is used to monitor the oil level. Traditional observation mirrors in the market may darken over time, reducing visibility. Therefore, the floating ball allows us to monitor the oil level even if the mirror darkens.
