Cusco 1C7 928 A Rear Differential Rigid Mount Collar Set Front Side

The Cusco Rear Differential Rigid Mount Collar Set (Front Side) is a precision-engineered performance upgrade designed to enhance rear differential stability and reduce unwanted drivetrain movement. This CNC-machined billet aluminum collar eliminates flex associated with factory rubber bushings, providing improved power transfer and vehicle responsiveness.

Key Features:

• CNC-machined billet aluminum construction in signature Cusco blue finish
• Designed to work with factory rubber bushings on the front side of the differential
• Reduces differential movement and drivetrain vibrations for improved handling precision
• Bolt-on installation with no special tools required
• Corrosion-resistant finish for long-lasting durability
• Precision-machined to exact OEM specifications for perfect fitment

Performance Benefits:

• Minimizes unnecessary rear differential movement during acceleration and spirited driving
• Improves gear shift feel and throttle response
• Reduces cabin vibrations caused by worn or soft differential bushings
• Enhances vehicle stability and cornering precision
• Ideal for street performance, track days, and aggressive driving applications

This rigid mount collar set sandwiches the top and bottom of the rear differential support mount bush with aluminum collars, creating a more solid connection that maintains differential position under load. The result is sharper handling response, reduced drivetrain shudder, and a more connected driving experience without compromising reliability.
