Description

The CUSCO Rear Differential Mount Collars are a precision-engineered drivetrain upgrade designed to enhance power delivery and traction response by reducing unwanted movement in the rear differential. By installing aluminum collars that sandwich the upper and lower sections of the factory differential support bushings, this kit effectively limits differential deflection, resulting in sharper throttle response, improved traction on acceleration, and more direct power transfer to the rear wheels—especially during upshifts and hard acceleration.

Product Highlights

🏗️ Aluminum Collar Bushing Reinforcement
Utilizes high-strength aluminum collars that clamp the factory differential mount bushings, significantly reducing compliance and limiting excessive differential movement under load.

⚡ Improved Throttle Response & Traction
By minimizing differential shift and rotation, power is transferred to the wheels more immediately and efficiently. This results in crisper throttle response, reduced drivetrain slack, and enhanced traction—particularly noticeable during upshifts and aggressive acceleration.

🔧 Simple, Non-Invasive Installation
The collars are designed as bolt-on additions that work with the existing factory bushings. Installation does not require pressing out old bushings or permanent modification, making it a straightforward and reversible upgrade.

🚀 Optimized for Performance Driving
Especially beneficial during spirited driving, track use, and launch scenarios where precise power delivery and immediate traction response are critical for performance and driver confidence.

🔩 Maintains OEM Comfort & NVH Levels
Unlike solid or full-replacement bushings, this collar system stiffens the mount without dramatically increasing noise, vibration, or harshness (NVH), preserving daily driving comfort while adding performance.
