Spec Clutch SP294 Stage 4 Clutch Kit - Carbon Semi-Metallic Puck Disc

The Spec Clutch SP294 Stage 4 Clutch Kit is engineered for heavily modified, high-output engines where maximum torque capacity, instantaneous engagement, and reduced rotating mass are the top priorities. This is a competition-grade clutch designed for drivers who demand uncompromising performance on the track.

The Stage 4 is a solid hub evolution of the Stage 3 design. The rigid, 8-rivet solid hub is heat-treated for exceptional strength and durability, delivering direct, immediate power transfer with no flex or slip under extreme load. Available in 3, 4, or 6-puck configurations, the carbon semi-metallic friction disc provides outstanding heat resistance and torque capacity well beyond what a street clutch can handle.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic puck disc (3, 4, or 6-puck rigid hub — specify at time of order)
• High-torque rigid 2-piece hub and carrier assembly
• Installation tool

Key Features:

• Solid 8-rivet hub — heat-treated for maximum strength and durability
• Carbon semi-metallic friction material — superior heat dissipation and torque capacity
• High-clamp pressure plate — maximizes clamping force for positive, aggressive engagement
• Multiple puck configurations — choose 3, 4, or 6 puck to match your specific application
• Instantaneous engagement — zero slip under hard launches or high-RPM shifts

Recommended Use: Drag Racing, Road Racing, Drift, Rallye, Circle Track, Pulling

Important Note: Due to the rigid hub design, the Stage 4 is not recommended for street driving. A SPEC flywheel is required; if reusing an existing flywheel, it must be resurfaced prior to installation. A minimum 450-mile break-in period is required before full-throttle engagement or drag launches.
