Cusco LSD RS1.5 EK9/DC2 Civic/Integra B16B/B18C

If you're pushing your 1996-2000 Honda Civic or 1997-2001 Acura Integra hard, especially on the track or during spirited driving, getting power down effectively is key. A limited-slip differential (LSD) like this Cusco RS model is designed to help you do just that. Unlike an open differential, which sends power to the wheel with the least traction, an LSD actively distributes torque between the drive wheels. This means more consistent grip, especially when accelerating out of corners or on surfaces with uneven traction.

This Cusco RS differential is a 1.5-way type. What that means in practice is it applies locking force during both acceleration and deceleration. During acceleration, it helps prevent wheelspin and keeps both wheels driving forward. When you lift off the throttle or brake, it still provides some locking action, which can help stabilize the car and improve turn-in response. This makes it a popular choice for performance driving where predictable handling is crucial. The RS series from Cusco is known for its smooth engagement and durability, built to handle the demands of performance driving. It uses a multi-plate clutch system that can be adjusted by changing the number and thickness of the clutch plates, allowing for fine-tuning of the locking characteristics to match your driving style and setup.

This differential is specifically designed to fit B16B and B18C engines found in certain Civic and Integra models. Installation involves removing the factory differential and installing this unit, which typically requires specialized tools and knowledge of drivetrain components. It's a significant upgrade for anyone looking to maximize their vehicle's performance potential, especially in autocross or road racing applications. Ensure you consult the manufacturer's installation instructions for proper setup and any additional components that may be needed for a complete installation.
