Cusco LSD Type-RS 1-Way Front CJ4A

This is the Cusco Type-RS 1-Way Limited Slip Differential (LSD) specifically for the CJ4A platform. If you're looking to significantly improve your vehicle's traction and handling, especially during cornering and acceleration out of turns, an LSD is a key component. This unit is designed to send more power to the wheel with better grip, reducing wheelspin and allowing you to put power down more effectively. The 1-way design means it primarily engages under acceleration, providing a more predictable feel when you're on the throttle.

Cusco is well-known for its performance drivetrain components, and the Type-RS is a popular choice for enthusiasts seeking a noticeable improvement in performance. This differential uses a unique cone clutch system that offers a smooth engagement and is built with durable materials to withstand the stresses of spirited driving. The 1-way engagement is particularly favored by many drivers for its straightforward behavior under acceleration, making it easier to manage the vehicle's dynamics. Installation involves replacing the factory open differential, which is a moderately involved process requiring specialized tools and knowledge of drivetrain components.

When installing this LSD, it's important to use the correct differential fluid recommended by Cusco to ensure proper break-in and long-term performance. You'll also want to ensure your axle seals and any related bearings are in good condition, as this is an opportune time to address them. This differential is a significant upgrade for anyone serious about maximizing their vehicle's performance potential on track or during spirited road use.
