Cusco 1.5 way LSD Type-RS Differentials for 1981-1985 DATSUN Fairlady Z - 280ZX S130 - LSD 161 L15 - (1985 1984 1983 1982 1981)

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. 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 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.

Pressure ring features dual profiles to switch between (1 way & 1.5 way) (1 way & 2 way) (1.5 way & 2 way) without purchasing additional components! Specialized cam profiles are available for custom orders.

• 1 way LSD
Specially suited for front wheel drive cars and AWD car front axles. Activates under acceleration, and acts as a true LSD when the throttle is off.
• 1.5 way LSD
Activates under acceleration while the under-steer under deceleration is less than on a 2 way LSD. Recommended for those who have a hard time with under-steer.
• 2 way LSD
Recommended on rear wheel drive cars and AWD car rear axles. Activates on both acceleration and deceleration. Recommended for those who prefer aggressive driving and big angle drifting.

All Cusco limited slip differentials have the option of adjusting the responsiveness and the locking characteristics the LSD by the combinaion 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.
