The Cusco LSD features high tension chrome molybdenium steel housing and gears. The Cusco LSD is up for the task of serious competition. With large oil windows for increased flow and Cusco's original groove cut technology for improved efficiency on the clutch plates, stability, and longevity is promoted. The 1-way can be converted to a 2-way or the other way around.

Cusco's performance limited slip differentials help put the power down. Cusco's Type-RS uses springs to absorb some of the initial torque application on the LSD, making for a gentler engagement and smoother transitions. Chatter is kept to a minimum, life is extended and oil change frequency is reduced.

In the RS Model, the activation pressure is applied to the same direction of the initial torque with the utilization of a coil spring. Therefore, the initial torque is set lower than the Cusco MZ LSD models enabling a smoother and quicker initial clutch plates engagement from non operational to fully functioning state, despite a low initial torque rating setting. The virtues of a low initial torque setting enables smooth turns even while the LSD mechanism is not activated. Because of the coil spring design, it provides overall gentle and stable operation.

RS Springs sit inside the pressure rings which helps engage the rear lock and the number of springs can be added or subtracted for personal customization.
