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

Differential Cover For AAM 11.5"/11.8″ 14 Bolts Rear Axle | SPELAB-4

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.

      08 GMC Sierra diff cover

      This looks so much beater than the rusty oem. Also like being able to see the diff oil level thru the sight glass. Also makes for easy fill and drain for regular maintenance.

      Great part!

      The diff cover fit great no issues looks amazing and was shipped and to the door faster than I was ready to work on it I was surprised I usually give it about a week for the part to show up but it was there within 3. Would definitely order again for my other vehicles and recommend.

      Great Performance Upgrade with Easy Installation

      Couldn't be happier with this performance upgrade, appearance and its features (fill and drain plugs, viewing port to check fluid level and condition). It was a simple installation, with a perfect fit for my 2016 Silverado 1500. I highly recommend this product.

      Excellent service and craftsmanship

      Diff cover was packaged extremely well and fit and finish was excellent with everything included. The only thing I would say is to include longer cover screws because of the difference in thickness from the thin factory cover. The screws included are the same as factory as far as length. 35mm in length cover screws would be spot on.
