Spec Clutch SB63PT Super Twin P-Trim Multi-Disc Clutch and Flywheel Kit

The SPEC SB63PT Super Twin P-Trim Multi-Disc Clutch Kit is an extreme-performance twin-disc clutch system engineered for street and track applications demanding 700–1,500 ft-lbs of torque capacity. Despite its race-proven capability, the Super Twin delivers near-stock pedal feel and drivability, making it equally at home on a daily driver as it is on a competition vehicle.

Built entirely from billet materials, the Super Twin features aircraft-grade aluminum and high-carbon billet steel machined to an industry-leading .001-inch tolerance for exceptional balance and precise actuation. Friction is handled by dampened, full-faced carbon-graphite discs — with organic, fiber, and full-metallic disc options also available to match your specific power level and driving style.

Key Features:

• Torque capacity: 700–1,500 ft-lbs — suitable for heavily modified street and race builds
• P-Trim carbon-composite dual-disc configuration for aggressive yet streetable engagement
• All-billet construction — smooth, quiet, and vibration-free operation
• No shimming or setup required — direct bolt-in installation
• Maintenance-free design with fully rebuildable assembly
• Rebuildable by SPEC or the end user; replacement components and rebuild services always available
• Includes billet flywheel and track-spec hardware
• SFI-approved clutch and flywheel components

Intended Use: Street, drag racing, drifting, road racing, time attack, pulling, and rallye.
