Spec Clutch SN334 Stage 4 Clutch Kit - Carbon Graphite Semi-Metallic

The Spec Clutch SN334 Stage 4 Clutch Kit is a high-performance clutch system built for heavily modified engines that demand maximum torque capacity and instantaneous, aggressive engagement. This is the solid hub evolution of the Stage 3, engineered specifically for motorsport applications where reliability under extreme load is non-negotiable.

The Stage 4 features a solid 8-rivet hub with a heat-treated disc assembly for superior strength and long-term durability. The kit is available in 3, 4, or 6-puck carbon graphite friction configurations to suit different performance goals — choose the 3-puck for the lightest rotating mass, the 6-puck for the smoothest engagement characteristics, or the 4-puck as an optimal balance of both. Note: due to the rigid hub design, this clutch is not recommended for street driving, though the 6-puck configuration is marginally more streetable than the 3 or 4-puck variants.

Kit Includes:

• High-clamp performance pressure plate
• Carbon graphite semi-metallic friction disc (3, 4, or 6-puck configuration)
• High-torque solid 8-rivet hub and disc assembly
• Release bearing
• Installation tool kit
