Cusco 1C7 008 AS High Volume Rear Differential Cover Silver Anodized Billet Aluminum

The Cusco 1C7 008 AS is a high-capacity billet aluminum rear differential cover designed to increase oil capacity and improve thermal management for demanding driving conditions. Manufactured from billet aluminum with a silver anodized finish, this performance upgrade provides enhanced protection for your differential components during sports driving and competition use.

Key Features:

• Increases oil capacity from 500cc (OEM) to 750cc (Cusco) - 50% more capacity
• Adds an additional 250ml of differential fluid capacity
• Features integrated cooling fins for improved heat dissipation
• Suppresses oil temperature rise and prevents LSD and differential gear troubles
• Direct bolt-on OE replacement design
• Precision machined from billet aluminum construction
• Silver anodized finish for corrosion resistance and aesthetic appeal

Performance Benefits:

Addresses the factory AWD system's tendency to enter limp mode during hard driving by increasing oil capacity and incorporating heat sink design. The increased fluid volume and enhanced cooling keep differential oil temperatures under control, preventing overheating-related failures and maintaining consistent performance during track days, spirited driving, and competition events.

Installation:

Direct bolt-on installation replaces the factory differential cover. Cannot be used with external oil cooler kits. Professional installation recommended for proper torque specifications and fluid refill.
