Cusco (w/ OEM) LSD Type RS 2Way Rear Mazda RX-7 FC3S

This is the Cusco LSD Type RS 2-Way rear differential for your Mazda RX-7 FC3S. You'll receive the differential unit itself, ready for installation. This is a significant upgrade for anyone looking to improve their RX-7's handling and traction, especially during spirited driving or track use. The Type RS is designed to offer a good balance between street drivability and performance on the track.

The Type RS is a clutch-type limited-slip differential, meaning it uses clutch plates to transfer torque to the wheel with more grip. The '2-Way' designation means it engages during both acceleration and deceleration. This provides consistent traction and stability when you're on the throttle and also helps to stabilize the rear end when you lift off or brake. This can make the car feel more predictable and planted through corners. Cusco is well-known for their performance drivetrain components, and this LSD is built with their experience in mind, using durable materials to handle the stresses of performance driving.

When installing a limited-slip differential, it's important to use the correct differential fluid. Always refer to the manufacturer's installation instructions for specific details on fluid type and any other required components or procedures. This differential is designed to work with your RX-7 FC3S's factory differential housing, making it a direct replacement for the stock unit, though professional installation is recommended due to the complexity of drivetrain work.
