We offer three different types of LSDs to suit your vehicle usage and motorsport needs, The Type RS, Type MZ, and the Hybrid Diff.

The primary difference between RS, MZ, and Hybrid units is the applied initial torque amount and the activation direction.
The MZ model LSD is designed where the activation pressure opposes the direction of the initial torque with the utilization of a cone spring. The LSD operation first becomes engaged when the opposing pressures start working against one another.

n 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 MZ model enables a smoother and quicker initial clutch plates engagement from a non operational to a fully functioning state even despite a low initial torque rating is set. The virtues of a low initial torque setting is that it enables a smooth turn even while the LSD mechanism is not activated. Because of the coil spring design, it provides overall gentle and stable operation. 

The Hybrid type has the smallest initial torque of all due to larger diameter coil spring.
The low initial torque which against to activation direction make the Hybrid LSD took advantage from RS and MZ.
