Description

The CUSCO Increased Capacity Differential Cover is a high-performance cooling and durability upgrade engineered to protect the rear differential and LSD under extreme driving conditions. Precision-machined from high-rigidity aluminum and featuring integrated cooling fins, this cover increases oil capacity by 50% (from 500cc to 750cc) and enhances heat dissipation, significantly reducing operating temperatures to prevent thermal breakdown, extend component life, and maintain consistent differential performance during track use, competition, and aggressive driving.

Product Highlights

🌡️ Enhanced Cooling & Thermal Management

• 50% Increased Oil Capacity: Holds 750cc of differential oil vs. the stock 500cc, providing a larger thermal reservoir to absorb and dissipate heat.

• Integrated Air-Cooling Fins: The machined aluminum body features optimized finning that increases surface area, promoting efficient air-cooling to lower operating temperatures under sustained load.

🛡️ Protection for LSD & Differential Components
By significantly reducing oil temperature rise, this cover helps prevent thermal degradation of the oil and clutch packs, protecting your investment in a performance LSD and ensuring consistent locking behavior and gear lubrication during extended track sessions.

🏗️ High-Rigidity Machined Aluminum Construction
CNC-machined from solid high-grade aluminum billet, providing exceptional strength and rigidity compared to the stock cast cover. This helps maintain precise gear alignment under high stress and reduces cover flex.

🎨 Premium Anodized Finishes
Available in two durable, corrosion-resistant finishes to match your engine bay aesthetics:

• Blue Anodized: Product Code 1C7-008-AL

• Silver Anodized: Product Code 1C7-008-AS

⏱️ Comprehensive Installation Process
Due to the need for differential oil service and precise sealing, installation has an estimated time of 5.0 hours. This process includes draining the old fluid, cleaning the mating surface, applying a fresh gasket/sealant, and refilling with the appropriate CUSCO LSD or gear oil.

Installation & Usage Notes

⚠️ Professional Installation Highly Recommended
The 5.0-hour estimate reflects the complexity of the job, which involves differential service, precise sealing, and proper fluid refill. Must be performed by a technician experienced in differential service.

⚙️ Mandatory Fluid Service & Compatibility
Installation requires draining the old differential fluid. Refill with the manufacturer-recommended oil, typically CUSCO LSD Gear Oil or an equivalent high-performance fluid suitable for your LSD type (clutch-type).

🏁 Essential for Track & High-Performance Use
This upgrade is highly recommended for any vehicle equipped with a performance LSD and used for track days, time attack, or repeated hard driving where differential temperatures can soar and cause performance loss or damage.
