The SPEC Magnum Super Twin is a full-size twin-disc clutch system built for the Tremec Magnum/T56 and engineered for high-torque, high-rpm applications. The P-Trim trim runs full-face organic 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. For 1993-1998 Toyota Supra 3.0L 2JZ-GE converted to a T56 transmission. Swap-specific clutch kit; confirm T56 input shaft and bellhousing before ordering.
