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. Fits Nissan Skyline R31 (1985-1989), R32 (1989-1994) and R33 (1993-1998). Chassis/engine-keyed import application; confirm transmission and input shaft spline before ordering.
