TYPE-RS Limited Slip Differential. In the RS Model, the activation pressure is applied to the same direction of the initial torque with the utilization of a coil spring. 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 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. These RS Springs apply constant pressure against the clutch plates at all times, resulting in minimal loss of initial torque over time. All Cusco limited slip differentials have the option of adjusting the responsiveness and the locking characteristics the LSD by the combination of each plate and its designation of how it is stacked. Cusco’s exclusive clutch plate grooves are cut radially enabling instant oil movement, thus improving efficiency and durability. The pressure ring contact surface is polished for an even and flat contact with the clutch plates. The exclusive Cusco Oil Through System enhances great oil circulation and supply to the necessary areas when used with the Cusco LSD Oil.
