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

If you're looking to get the most out of your performance vehicle on the track or in spirited driving situations, a limited-slip differential (LSD) can make a significant difference in how power is put down. This Cusco RS Series LSD is designed to improve traction and handling by controlling the speed difference between your drive wheels. It's a 1-way and 1.5-way adjustable unit, meaning it engages under acceleration and can also provide some locking effect under deceleration, depending on the setting. This helps prevent wheelspin and allows for more precise control when cornering.

The RS Series LSD from Cusco is a well-built unit that uses a unique cone spring system. This system allows for a wide range of torque sensitivity adjustments, from a mild effect to a more aggressive lock-up. The internal components are made from durable materials designed to withstand the demands of performance driving. Installation involves replacing your factory open or limited-slip differential with this unit, which requires specialized knowledge and tools. It's important to follow the manufacturer's break-in procedure to ensure the longevity of the LSD.

This particular differential is a 1-way and 1.5-way adjustable unit. The '1-way' setting means it primarily locks under acceleration, helping to put power down more evenly to both wheels when you're on the throttle. The '1.5-way' setting adds a degree of locking effect during deceleration, which can help stabilize the car during corner entry and mid-corner. The adjustability allows you to fine-tune the differential's behavior to suit your driving style and track conditions. For optimal performance and longevity, it's recommended to use high-quality differential fluid and adhere to Cusco's recommended maintenance schedule.
