Cusco Type RS LSD 1 Way - Front 04-21 STI

In the RS model, the activation pressure aligns with the direction of the initial torque, facilitated by a coil spring. Consequently, the initial torque is set at a lower level compared to the MZ model, allowing for smoother and quicker engagement of clutch plates from an inactive to an active state. Despite the lower initial torque rating, this setup enables seamless turning even when the LSD mechanism is not engaged. Thanks to the coil spring design, overall operation remains gentle and stable.

The RS Springs are positioned inside the pressure rings to assist in engaging the rear lock, and users can adjust the number of springs according to their personal preferences for customization.
