Spec Clutch SL55ST Super Twin ST-Trim Multiplate Clutch Kit

The SPEC SL55ST Super Twin ST-Trim Multiplate Clutch Kit is engineered for high-output street and track applications demanding between 700 and 1,500 ft-lbs of torque. Despite its extreme torque capacity, the Super Twin delivers near-stock drivability, making it equally at home on a daily commute as it is at the drag strip, road course, or drift event.

• Industry-leading .001-inch machining tolerances for perfect rotational balance and precise actuation
• Dampened, full-faced carbon graphite friction discs for consistent, controlled engagement
• No shimming or setup required — true bolt-in installation straight from the box
• Maintenance-free operation with tremendous life expectancy under extreme use
• User-rebuildable design — can be serviced by SPEC or the end user; replacement components and rebuild services are always available
• Friction options available: organic, fiber, and full metallic disc configurations
• Includes flywheel and track-spec hardware in every kit
• Designed, hand-built, and tested in the U.S.A.
