Spec Clutch SF204-2 Stage 4 Performance Clutch Kit with Carbon-Graphite Disc

The SPEC SF204-2 Stage 4 Clutch Kit is a high-performance, solid-hub clutch designed for serious motorsport applications. Built as a step up from the Stage 3, it features a solid 8-rivet hub with a heat-treated assembly for maximum strength and durability under extreme loads.

This kit is available in 3, 4, or 6-puck disc configurations, allowing you to tailor engagement characteristics to your specific driving style. The 3-puck option delivers the lightest rotating mass, while the 6-puck provides the smoothest engagement and is the only configuration considered street-drivable. The 4-puck strikes a balance between the two extremes. Note that due to the rigid solid hub design, this clutch is not considered street-friendly regardless of puck count.

Key Features:

• High-clamp pressure plate for maximum torque holding capacity
• Carbon-graphite friction material for aggressive grip and heat resistance
• Solid 8-rivet hub and disc assembly heat-treated for strength and durability
• 8.875 in. disc diameter with 23-spline input and 1.031 in. shaft diameter
• Flywheel not included — single disc design
• Bearing and alignment tool kit included for straightforward installation

Ideal for drag racing, road racing, rally, drifting, and pulling, the SPEC Stage 4 is a proven choice for high-demand competition environments where maximum holding power takes priority over daily drivability.
