Spec Clutch SC10SST Super Twin SS-Trim Multiplate Clutch Kit

The Spec Clutch SC10SST Super Twin SS-Trim is a high-performance dual-disc clutch kit engineered for street and track applications in vehicles producing extreme horsepower and torque — rated to handle 700 to 1,500 ft-lbs of torque. Despite its competition-level capability, the Super Twin delivers near-stock drivability, making it equally suited for daily driving and all-out racing use.

The SS-Trim designation features dampened, full-faced carbon composite/Kevlar friction discs that provide consistent, progressive engagement under demanding conditions. The entire assembly is constructed from aircraft-grade aluminum and high-carbon billet steel, precision-milled to an industry-leading .001-inch tolerance for perfect balance and smooth actuation.
