Spec Clutch SF05PT Super Twin P-Trim Multi-Disc Clutch Kit

The SPEC SF05PT Super Twin P-Trim Multi-Disc Clutch Kit is engineered for street and track use in high-output vehicles producing extreme horsepower and torque — rated to handle 700 to 1,500 ft-lbs of torque. Unlike conventional high-performance clutches that force a compromise between drivability and capability, the Super Twin delivers near-stock engagement feel alongside massive torque capacity, maintenance-free operation, and a true bolt-in installation with no shimming or setup required.

Every Super Twin assembly is built from all-billet construction using aircraft-grade aluminum and high-carbon billet steel, machined to industry-leading .001-inch tolerances for perfect rotational balance and precise actuation. The result is a clutch system that remains remarkably smooth and quiet even under extreme load.
