Spec Clutch SD80PT Super Twin Multiplate Clutch Kit P-Trim

The Spec Clutch SD80PT Super Twin Multiplate Clutch Kit (P-Trim) is an extreme-duty twin-disc clutch and flywheel assembly engineered for high-performance street and track applications. Designed to handle 700–1,500 ft-lbs of torque, the Super Twin delivers near-stock drivability without sacrificing the holding power demanded by heavily modified, forced-induction, or race-prepared vehicles.

Built entirely from aircraft-grade aluminum and high-carbon billet steel, each Super Twin assembly is machined to an industry-leading .001-inch tolerance for perfect rotational balance and precise actuation. Despite its race-level performance capability, the all-billet construction keeps engagement smooth and quiet, making it equally at home on the street as on the track.
