Cusco 692 928 A Rear Differential Mount Collar

The Cusco Rear Differential Mount Collar is a performance drivetrain upgrade designed to provide improved stability and responsiveness by reinforcing the rear differential mounting system. These aluminum inserts connect directly to the rear crossmember, offering a more direct connection than traditional rubber bushings.

Key Features:

• Provides stabilization to the rear differential by reinforcing the bushings without requiring removal of factory bushings
• 100% bolt-on design that requires no modifications
• Sold as a pair and comes ready for installation
• Improves shifting response and reduces differential mount movement during acceleration
• Provides more direct response compared to reinforcement bushings
• Constructed from high-quality aluminum for durability

Developed during Cusco's product development for the GRB Impreza, these differential mount collars deliver noticeable improvements in drivetrain stability and power transfer. The simple bolt-on installation makes this an accessible upgrade for enthusiasts looking to reduce drivetrain deflection and improve throttle response during aggressive driving.
