Differential Cover GM 8.5″/8.6″ 10 Bolts Rear Axle | SPELAB

Function:

Protects the differential, seals the differential, stores differential fluid.

Note: The year and model may not guarantee compatibility. Please confirm whether the axle is GM 8.5″/8.6″ 10 Bolts.

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.

5. The outside with black wrinkle paint providing rust resistance.
