The SPEC SN35ST-2 Super Twin Multi-Disc Clutch Kit (ST-Trim) is a high-performance twin-disc clutch system engineered for street and track use in extreme high-horsepower builds. Rated to handle 700–1,500 ft-lbs of torque, this kit delivers the holding power demanded by serious performance applications without sacrificing everyday drivability.
