Spec Clutch SH124 Stage 4 Performance Clutch Kit

The Spec Clutch SH124 Stage 4 Clutch Kit is a race-grade clutch system engineered for heavily modified engines demanding maximum torque capacity and instantaneous engagement. Built as the solid-hub evolution of the Stage 3, this kit is purpose-built for competitive motorsport applications where performance takes priority over daily driveability.

Key Features:

• Solid 8-rivet hub — rigid hub design eliminates deflection for direct, immediate power transfer
• Heat-treated assembly — hub and disc assembly is heat treated for enhanced strength and long-term durability under high-stress conditions
• Carbon semi-metallic friction material — high-performance carbon-graphite puck disc available in 3, 4, or 6-puck configurations
• High clamp pressure plate — increased clamping force handles elevated torque loads from modified engines
• 3, 4, or 6-puck configuration options — choose 3-puck for the lightest weight, 6-puck for the smoothest engagement, or 4-puck for a balance of both
• Torque capacity: 298 ft-lbs
• Kit includes: pressure plate, disc, release bearing, and tool kit (select configurations)

Intended Use: Drag Racing, Drift, Road Racing, Rallye, Pulling, Circle Track

Important Note: Due to the rigid solid hub design, this clutch is not recommended for street use. The 6-puck configuration offers the most streetable engagement of the available options, but full street use is not advised. A minimum 450-mile break-in period under city/stop-and-go driving is required before full-throttle engagement or drag launches. Flywheel resurfacing or replacement is strongly recommended prior to installation.
