Description

The CUSCO Rear Differential Carrier Mount Collar is a performance drivetrain component engineered to enhance power delivery and stability by reducing unwanted movement in the rear differential carrier mount. By installing a precision-machined aluminum collar that sandwiches the factory carrier mount bushing, this upgrade effectively limits deflection, resulting in sharper throttle response, improved traction under acceleration, and more consistent power transfer—especially during upshifts and dynamic driving.

Product Highlights

🏗️ Aluminum Collar for Carrier Mount Reinforcement
Utilizes a high-strength aluminum collar designed to clamp and reinforce the factory rear differential carrier mount bushing, reducing compliance and minimizing differential carrier movement under load.

⚡ Enhanced Drivetrain Response & Traction
By stabilizing the differential carrier, power is transferred to the wheels with less delay and deflection. This leads to crisper throttle response, reduced drivetrain slack, and improved traction—particularly noticeable during upshifts and hard acceleration out of corners.

🔧 Targeted, Non-Invasive Installation
The collar is engineered as a bolt-on addition that works with the existing bushing, requiring no pressing or permanent modification to the vehicle’s mounting points, making it a straightforward and reversible performance upgrade.

⏱️ Efficient Professional Installation
With an estimated installation time of 1.5 hours, this collar can be integrated efficiently by experienced technicians, offering a meaningful performance gain without extensive labor.

🏁 Optimized for Dynamic & Performance Driving
Ideal for spirited street driving, track use, and situations where precise and immediate power delivery is critical for maintaining momentum, stability, and driver confidence.
