Cusco CZ4A LSD RS F Compact 1.5(1&1.5)

The Cusco RS F Compact 1.5-way limited-slip differential is built with a compact housing, allowing it to fit into transmissions where a standard LSD might not. This specific unit is designed for a 1.5-way engagement, meaning it provides locking force during both acceleration and deceleration, but with a more aggressive lock on acceleration. This setup is ideal for performance driving where consistent traction is crucial for cornering and power delivery.

Constructed with a durable, well-built internal mechanism, this LSD utilizes a multi-plate design to achieve its locking effect. The 1.5-way characteristic offers a noticeable improvement in stability and control when exiting corners, helping to reduce wheel spin and put power down more effectively. Its compact nature is a key design choice, enabling installation in a wider range of vehicle applications that might have tight space constraints within the transmission or differential housing.

When installing a limited-slip differential like this, it's important to use the correct differential fluid recommended by Cusco. This ensures the clutch plates within the LSD operate smoothly and effectively, and it helps to prevent premature wear. Proper installation and fluid maintenance are key to getting the most out of this performance-oriented component and ensuring its longevity.
