Cusco 1C7 928 B Rear Differential Mount Collar Bushing Rear Side

The Cusco 1C7 928 B Rear Differential Mount Collar is a precision-engineered aluminum reinforcement component designed to minimize rear differential movement under high-performance driving conditions. By sandwiching the rear mount of the differential carrier with this rigid aluminum collar, the part significantly reduces unwanted differential deflection that can compromise power delivery and shift quality.

Key Features:

• Constructed from high-grade aluminum for strength and light weight
• Anodized in Cusco's signature blue finish for corrosion resistance and distinctive appearance
• Reduces differential movement for improved power transfer efficiency
• Enhances shift feel and responsiveness during spirited driving
• Provides more direct connection between drivetrain and chassis
• Approximately 1.5 hour installation time
• Bolts directly to existing mounting points without bushings removal

This rear-side differential mount collar works by reinforcing the factory differential bushings, creating a more rigid mounting system that translates to quicker acceleration response and more precise gear changes. The aluminum construction maintains durability while keeping unsprung weight to a minimum, making it an ideal upgrade for performance-focused applications including track use, autocross, and spirited street driving.
