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

Function:

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

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.

---tab FAQS---

Q1: What is a differential cover?
A1: A differential cover is a protective cover for the differential housing, helping to shield the gears and differential fluid from debris and damage.

Q2: Why should I upgrade my differential cover?
A2: Upgrading to a high-performance differential cover can improve cooling, increase oil capacity, and enhance durability, leading to better overall performance and longevity of the differential.

Q3: How does a finned differential cover improve cooling?
A3: The fins increase the surface area, which helps dissipate heat more efficiently, reducing the operating temperature of the differential.

Q4: Is a billet aluminum differential cover better than a cast aluminum one?
A4: Yes, billet aluminum covers are typically stronger and more durable than cast aluminum covers due to their superior material properties and manufacturing process.

Q5: How do I know if a differential cover will fit my vehicle?
A5: Check the product specifications and fitment guide provided by the manufacturer to ensure compatibility with your vehicle's make, model, and year.

Q6: What tools are needed to install a differential cover?
A6: Common tools include a socket set, torque wrench, gasket scraper, and differential fluid. Some installations may require additional specific tools.

Q7: How often should I change the differential fluid?
A7: It's recommended to change the differential fluid every 30,000 to 60,000 miles, but always refer to your vehicle's owner manual for specific intervals.

Q8: Can I install a differential cover myself, or do I need a professional?
A8: Many differential covers can be installed by a knowledgeable DIYer with basic mechanical skills and tools. However, if you're unsure, it's best to seek professional help.

Q9: Will an upgraded differential cover void my vehicle's warranty?
A9: It depends on the manufacturer and the terms of your warranty. Check with your vehicle's manufacturer or dealer for specific warranty information.

Q10: What are the benefits of increased oil capacity in a differential cover?
A10: Increased oil capacity improves lubrication and cooling, which can enhance the differential's performance and longevity, especially under heavy use or high-stress conditions.
