Spec Clutch SC884 Stage 4 Race Clutch Kit - Carbon Semi-Metallic Puck Disc

The Spec Clutch SC884 Stage 4 Clutch Kit is a high-performance racing clutch engineered for heavily modified engines demanding maximum torque capacity and instantaneous engagement. As a solid hub evolution of the Stage 3, this kit is built exclusively for competition use where aggressive, direct power transfer takes priority over street comfort.

Key Features:

• Solid 8-rivet rigid hub — heat-treated for exceptional strength and durability under race conditions
• High-clamp pressure plate — engineered to handle elevated torque loads beyond standard street clutch capability
• Carbon semi-metallic puck disc — available in 3, 4, or 6-puck configurations to suit your specific application
• Rigid 2-piece carrier assembly — provides instantaneous, no-slip engagement for consistent launches and aggressive driving
• SFI approved — meets sanctioned racing safety standards
• Torque rating up to 443 ft-lbs (application-specific)

Puck Configuration Guide:

• 3-puck — lightest rotating mass, maximum power transfer
• 4-puck — balanced compromise between weight and engagement smoothness
• 6-puck — smoothest engagement of the three options

Kit Includes: High-clamp pressure plate, carbon semi-metallic rigid puck disc with high-torque rigid hub and carrier assembly, release bearing, and installation tool kit.

Recommended Applications: Drag racing, road racing, drifting, rallye, pulling, and circle track. Not recommended for daily street driving due to harsh, instantaneous engagement characteristics inherent to the rigid hub design.
