Spec Clutch SN35SST Super Twin SS-Trim Multi-Plate Clutch and Flywheel Kit

The Spec Clutch SN35SST Super Twin SS-Trim is a high-performance dual-disc clutch and flywheel kit engineered for street and track applications demanding extreme torque capacity — rated to handle 700–1,500 ft-lbs of torque. Designed for builds where a single-disc clutch simply won't cut it, the Super Twin delivers the holding power of a race clutch while maintaining near-stock drivability for daily or street use.

Key Features:

• Dual-disc (multi-plate) design — Carbon composite/Kevlar® full-face, unsprung hub friction discs provide exceptional torque transfer and heat resistance

• Near-stock drivability — Engineered to feel manageable on the street despite extreme torque capacity

• Maintenance-free operation — Smooth and quiet under all driving conditions
