Spec Clutch SFG5SST-3 Super Twin SS-Trim Clutch and Flywheel Kit

The Spec Clutch SFG5SST-3 Super Twin SS-Trim Clutch and Flywheel Kit is engineered for high-output builds demanding serious drivetrain capability. Rated to handle 700–1,500 ft-lbs of torque, this twin-disc clutch and flywheel kit delivers race-level holding power while maintaining near-stock street drivability — making it equally at home on the drag strip, road course, or daily commute.

Built from aircraft-grade aluminum and high-carbon billet steel, every component is CNC-milled to an industry-leading .001-inch tolerance for perfect rotational balance and precise actuation. Friction is generated by dampened, full-faced carbon graphite discs, and the SS-Trim designation indicates a Hybrid Kevlar/Semi-Metallic puck disc configuration — offering an excellent balance of street smoothness and aggressive grip. Organic, fiber, and full-metallic disc options are also available within the Super Twin lineup.
