Vehicle Compatibility (GM with 10.5″ 14-Bolt Rear Axle)

GM also produced 9.5″ and 11.5/11.8″ 14-bolt axles — different size housings and covers, so this cover will not fit those. Always confirm your rear axle size by measuring the ring gear diameter or checking build sheets before ordering.

---tab Description---

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.
