Cusco LSD RS1.5 JZA80 SUPRA

This is the Cusco RS 1.5-way limited-slip differential (LSD) specifically for the JZA80 Toyota Supra. If you're looking to significantly improve your Supra's traction and handling, especially during spirited driving or track use, this differential is a substantial upgrade. It's designed to put power down more effectively by controlling wheel spin during acceleration, both in a straight line and through corners.

The RS series from Cusco is known for its advanced design, featuring a unique cam mechanism that allows for adjustable engagement. This 1.5-way setup means it provides strong locking force during acceleration, but a milder, more controlled locking effect during deceleration. This balance is crucial for predictable handling, reducing understeer and making the car feel more stable when you lift off the throttle. The internal components are well-made, utilizing high-strength materials to withstand the demands of performance driving. Installation involves replacing your factory differential, which is a complex job that typically requires specialized tools and knowledge, often best handled by a professional mechanic experienced with drivetrain work.

When installing this LSD, it's important to use the correct differential fluid recommended by Cusco to ensure proper break-in and long-term performance. This unit is designed to work with the stock transmission and axle components of the JZA80 Supra, but always confirm compatibility with your specific vehicle's drivetrain configuration. Proper setup and fluid maintenance are key to unlocking the full potential of this high-performance differential.
