Cusco 1C7 008 AL High Capacity Rear Differential Cover Blue Anodized Billet Aluminum

The Cusco 1C7 008 AL is a high-capacity rear differential cover designed to enhance cooling and protection for Toyota GR Yaris and GR Corolla models. This performance upgrade is precision-machined from billet aluminum and features a distinctive blue anodized finish with integrated cooling fins.

Key Features:

• Increased oil capacity: 750cc (Cusco) vs. 500cc (OEM stock) - 50% more fluid volume
• CNC-machined billet aluminum construction for superior strength and heat dissipation
• Cooling fin design helps reduce differential oil temperatures during spirited driving
• Blue anodized finish adds visual appeal while protecting against corrosion
• Direct bolt-on installation as OE replacement type
• Designed for track use, competitive driving, and high-performance applications

Performance Benefits:

By increasing differential oil capacity by 250cc, this cover helps suppress oil temperature rise during demanding driving conditions. Lower operating temperatures protect the limited-slip differential (LSD) and ring-and-pinion gears from premature wear and potential failure. The enhanced thermal management is particularly beneficial during track days, autocross, rally, and spirited street driving.

Note: This differential cover cannot be used in conjunction with external oil cooler kits.
