Spec Clutch SN85PT-2 Super Twin P-Trim Multi-Disc Clutch Kit

The Spec Clutch SN85PT-2 is a Super Twin multi-disc clutch kit in P-Trim, purpose-built for high-output street and track applications demanding 700 to 1,500 ft-lbs of torque. Designed to handle extreme power while maintaining near-stock drivability, this twin-disc clutch system is a bolt-in solution requiring no shimming or setup, and it operates maintenance-free once installed.

Constructed entirely from aircraft-grade aluminum and high-carbon billet steel milled to an industry-leading .001-inch tolerance, each Super Twin assembly delivers exceptional balance and precise actuation. The all-billet construction results in a unit that is both smooth and quiet under all driving conditions. Friction is provided by dampened, full-faced carbon graphite discs, with organic, fiber, and full-metallic disc options also available to suit your specific power level and driving style.
