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.
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.Hybrid LSD 1Way, Position: Rear
