Spec Clutch ST484 Stage 4 Performance Clutch Kit - Carbon-Graphite Puck Disc

The SPEC ST484 Stage 4 Clutch Kit is a high-performance, solid hub clutch designed for serious motorsport applications including drag racing, road racing, rallye, drifting, and pulling competitions. Built as a solid hub evolution of the SPEC Stage 3, this kit delivers maximum torque capacity and durability where it counts most.

The solid 8-rivet hub is heat treated for exceptional strength, and the carbon-graphite friction disc is available in a 3-puck, 4-puck, or 6-puck configuration to match your specific performance needs. The 3-puck disc offers the lightest rotating mass for maximum rev response, the 6-puck provides the smoothest engagement and remains marginally street drivable, while the 4-puck strikes an ideal balance between the two. Note that due to the rigid solid hub design, this kit is not recommended for everyday street driving.

Key Features:

• Solid 8-rivet hub — heat treated for maximum strength and durability
• High-clamp pressure plate — increases clamping force over stock for higher torque capacity
• Carbon-graphite friction material — superior heat resistance and torque transfer for race applications
• Available in 3, 4, or 6-puck configurations — choose based on your weight, engagement, and drivability priorities
• Includes bearing and alignment tool kit — everything needed for a complete installation

Intended Applications: Drag Racing, Road Racing, Rallye, Drifting, Pulling
