Upgrade your Dodge RAM front differential with the SPELAB Heavy-Duty Differential Cover for AAM 9.25″ 14-Bolt Axles, engineered for strength, protection, and reliability in demanding driving conditions.
Designed specifically for 2003–2013 Dodge RAM 2500 & 3500 4WD trucks, this differential cover delivers enhanced durability and improved sealing compared to the factory stamped steel cover.
Key Features
Heavy-Duty Construction
Built from high-strength material to resist impacts, deformation, and off-road hazards.
Precision Machined Fitment
Designed exclusively for AAM 9.25″ 14-bolt front axles to ensure a proper seal and hassle-free installation.
Improved Protection
Helps safeguard internal differential components from debris, rocks, and fluid leaks.
Leak-Resistant Design
Reinforced flange surface promotes better gasket contact and long-term oil sealing.
Innovative points:
1. The external heat sink design increases the contact area between the differential cover and the surrounding air, enhancing heat dissipation performance.
2. 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.
3. 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.
4. 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.
