Cusco PRO-ADJ LSD RS FC FD3S

This listing is for the Cusco PRO-ADJ LSD RS FC FD3S, a clutch-type limited slip differential designed for performance applications. You'll receive the differential unit itself, ready for installation into your compatible vehicle. This unit is built to enhance traction and handling, especially during spirited driving or when exiting corners. It works by mechanically biasing torque to the wheel with more grip, helping to prevent wheelspin and improve acceleration out of turns. The RS (Real Speed) designation indicates a specific design focus for improved performance characteristics.

Cusco is well-known for its performance drivetrain components, and this LSD is a prime example of their engineering. It features a multi-plate clutch system that can be adjusted to fine-tune the locking force, allowing you to dial in the differential's behavior to match your driving style and track conditions. This adjustability is key for serious tuners who want to optimize their vehicle's handling. The construction is solid, intended to withstand the rigors of performance driving. Proper installation by a qualified mechanic is recommended, as it involves working with the drivetrain and requires specific tools and procedures to ensure correct setup and function.

When installing a limited slip differential like this, it's important to use the correct differential fluid as specified by Cusco. This fluid is crucial for the proper operation and longevity of the clutch plates. You may also need to consider other drivetrain components, such as axle seals or bearings, depending on the condition of your existing parts and the specific installation requirements for your vehicle. Consulting the manufacturer's installation guide is always the best practice for a successful build.
