The SPEC Super Twin is a full-size twin-disc clutch system engineered for high-torque, high-rpm applications. The SS-Trim trim runs sprung semi-metallic friction material across two discs for a large jump in holding capacity over a single-disc clutch while staying streetable, and the kit ships complete with pressure plate, discs, flywheel, and the hardware needed for installation.
