Spec Clutch SC09ET Super Twin Multiplate Clutch Kit ET-Trim

The SPEC SC09ET Super Twin Multiplate Clutch Kit is a high-performance twin-disc clutch system engineered for street and track applications in vehicles producing extreme horsepower and torque. Rated to handle 700–1,500 ft-lbs of torque, this kit delivers the clamping force needed for heavily modified and high-output builds while maintaining near-stock drivability.

Built with aircraft-grade aluminum and high-carbon billet steel, the Super Twin is precision-machined to industry-leading .001-inch tolerances for perfect balance and smooth, consistent actuation. The dual-disc design maximizes friction surface area for progressive engagement and superior heat management, making it equally at home on the street or the track.

Key Features:

• Torque capacity: 700–1,500 ft-lbs — ideal for forced induction, high-compression, and heavily modified engines
• All-billet construction — smooth, quiet operation with aircraft-grade aluminum and high-carbon billet steel components
• Dampened, full-faced carbon graphite friction discs for progressive, controlled engagement
• Available in multiple trim levels: SS-Trim, P-Trim, ST-Trim, E-Trim, and ET-Trim — friction disc and pressure plate configurations vary by trim to match driving style and power level
• No shimming or setup required — bolt-in installation straight out of the box
• Maintenance-free design with tremendous service life expectancy
• Fully rebuildable by SPEC or the end user; replacement components and rebuild services are always available
• Flywheel and track-spec hardware included in every kit
• Suitable for: street, drag racing, drifting, road racing, time attack, pulling, and rally

The SPEC SC09ET Super Twin is the go-to solution for enthusiasts and competitors who have outgrown single-disc clutch systems and demand a reliable, high-capacity twin-disc setup without sacrificing everyday usability.
