Spec Clutch SK244 Stage 4 Performance Clutch Kit

The Spec Clutch SK244 Stage 4 Clutch Kit is a high-performance, solid-hub clutch system engineered for drivers who demand maximum torque capacity and durability. Built as a solid-hub evolution of the Stage 3 design, this kit features a rigid 8-rivet solid hub disc assembly that has been heat-treated for exceptional strength and long-term reliability under extreme load conditions.

The SK244 is available in 3-puck, 4-puck, and 6-puck configurations to suit a range of performance driving styles. The 3-puck disc offers the lightest rotational mass for the quickest throttle response, while the 6-puck configuration delivers the smoothest engagement of the three and remains marginally street drivable. The 4-puck strikes a balance between the two, making it a versatile choice for mixed-use builds. Note that due to the rigid hub design, this clutch is not recommended for everyday street driving regardless of puck configuration.

Key Features:

• Solid 8-rivet hub — heat-treated for high-torque strength and durability
• High-clamp pressure plate — increases clamping force over stock for improved power transfer
• Carbon-graphite friction material — provides excellent heat resistance and torque capacity
• Available in 3, 4, or 6-puck disc configurations — select based on your driving application
• Includes bearing and installation tool kit — everything needed for a complete clutch replacement

The Spec SK244 Stage 4 is purpose-built for drag racing, road racing, rallye, drifting, and pulling applications where outright performance and holding capacity are the priority over daily drivability.
