Spec Clutch SB884 Stage 4 Performance Clutch Kit - Carbon Semi-Metallic

The Spec Clutch SB884 Stage 4 Clutch Kit is a high-performance, competition-grade clutch system engineered for heavily modified engines demanding maximum torque capacity and instantaneous engagement. Built for drivers who prioritize raw performance over street comfort, the Stage 4 is the go-to choice for drag racing, road racing, drifting, rallye, pulling, and circle track applications.

The Stage 4 is a solid hub version of the Stage 3 clutch. The hub features a solid 8-rivet design with a heat-treated assembly for exceptional strength and long-term durability under extreme load. The carbon semi-metallic friction disc is available in 3-puck, 4-puck, or 6-puck configurations to suit your specific performance needs.

Puck Configuration Guide:

• 3-Puck: Lightest weight option — ideal for maximum performance where rotating mass reduction is critical
• 4-Puck: Balanced compromise between weight savings and engagement feel
• 6-Puck: Smoothest engagement of the three — marginally more streetable, though the rigid hub design is not recommended for daily street driving

Kit Includes:

• High clamp load performance pressure plate
• Carbon semi-metallic friction disc (3, 4, or 6-puck)
• High-torque rigid hub and carrier assembly
• Throwout bearing
• Installation tool kit

Intended Use: Drag Racing, Drifting, Road Racing, Rallye, Pulling, Circle Track

Note: Due to the rigid hub design, the Stage 4 is not recommended for street use. Harsh engagement characteristics are inherent to this competition-level clutch.
