Spec Clutch SZ204-5 Stage 4 Clutch Kit - Carbon-Graphite 3/4/6 Puck

The SPEC SZ204-5 Stage 4 Clutch Kit is a race-focused, solid-hub clutch designed for drivers who demand maximum torque capacity and durability. Built as the solid-hub evolution of the SPEC Stage 3, this kit steps up the aggression with an 8-rivet solid hub disc assembly that has been heat-treated for exceptional strength and long-term reliability under extreme conditions.

The SZ204-5 is available in 3-puck, 4-puck, and 6-puck configurations, giving you the flexibility to tune the engagement characteristics to your driving style. The 3-puck disc delivers the lightest rotating mass, ideal for applications where quick rev response is critical. The 6-puck configuration offers the smoothest engagement of the three and is the only puck count considered street-drivable — though the rigid solid hub means this kit is not recommended as a daily driver. The 4-puck strikes a balance between weight savings and engagement smoothness, making it a popular all-around choice for motorsport use.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Carbon-graphite friction material for aggressive bite and heat resistance
• Solid 8-rivet hub disc assembly, heat-treated for strength and durability
• Available in 3, 4, or 6-puck configurations to suit your performance needs
• Bearing and installation tool kit included

The Stage 4 is purpose-built for drag racing, road racing, rally, drifting, and pulling applications where maximum clutch performance is non-negotiable. Note: Due to the rigid solid hub design, this clutch kit is not recommended for street or daily driving use, even in the 6-puck configuration.
