Spec Clutch SB93PT Super Twin Multi-Disc Clutch & Flywheel Kit - P-Trim

The Spec Clutch SB93PT Super Twin Multi-Disc Clutch Kit is engineered for street and track applications demanding extreme power handling, rated for 700 to 1,500 ft-lbs of torque. Despite its race-bred capability, the Super Twin delivers near-stock pedal feel and drivability, making it equally at home on a daily commute or a competition circuit.

Built entirely from billet materials, this multiplate clutch system runs smooth and quiet. The housing and internals are precision-machined from aircraft-grade aluminum and high-carbon billet steel to tolerances of just .001 inch, ensuring perfect rotational balance and consistent actuation under all conditions. The P-Trim designation features dampened, full-faced carbon graphite friction discs with an unsprung hub for direct, responsive engagement.
