Cusco LSD RS 1-way (1/2-way) CZ4A Evo X (AYC models ONLY) Side Bearing not included

The Cusco LSD RS 1-way (1/2-way) differential is built with a unique cam mechanism that allows for adjustable lock-up characteristics. This means you can fine-tune how the differential behaves under acceleration and deceleration, giving you more control when you need it most. Specifically designed for the Mitsubishi Lancer Evolution X models equipped with Active Yaw Control (AYC), this limited-slip differential is a significant upgrade for performance driving.

This differential uses a 1-way (or 1.5-way, depending on adjustment) engagement system. Under acceleration, it locks up to distribute power to both rear wheels, enhancing traction out of corners and improving acceleration. When you lift off the throttle or brake, the lock-up disengages more smoothly than a traditional 2-way differential, which can help with stability during corner entry and mid-corner. The RS model features a refined internal design for smoother engagement and reduced noise, making it a more street-friendly option compared to some other performance differentials.

Installation of this differential requires specialized knowledge and tools, and it is crucial to ensure proper setup for optimal performance and longevity. The side bearings are not included with this unit and must be sourced separately. This is a serious upgrade for Evo X owners looking to maximize their vehicle's handling capabilities on the track or during spirited driving.
