The SPEC SN46ST Super Twin Multiplate Clutch Kit is engineered for high-performance street and track applications, designed to handle extreme power outputs ranging from 700 to 1,500 ft-lbs of torque. Despite its race-ready capability, the Super Twin delivers near-stock drivability, making it equally at home on daily-driven performance builds and dedicated competition vehicles.
