Spec Clutch SN344 Stage 4 Race Clutch Kit - Carbon Semi-Metallic Multi-Puck

The Spec Clutch SN344 Stage 4 Clutch Kit is a race-oriented, solid hub clutch system engineered for heavily modified engines demanding maximum torque capacity and instantaneous engagement. Rated up to 350 ft-lbs of torque, this kit is purpose-built for competitive motorsport applications where performance takes priority over daily drivability.

Key Features:

• Solid 8-rivet hub — heat-treated for superior strength and long-term durability under race conditions
• High-clamp performance pressure plate — maximizes clamping force for aggressive power transfer
• Carbon semi-metallic friction disc — available in 3, 4, or 6-puck configurations to match your specific racing needs
• Puck configuration options: 3-puck for the lightest possible weight, 6-puck for the smoothest engagement, and 4-puck as a balanced compromise between the two
• SFI Approved — meets the Safety Foundation International standards for racing clutch components
• Complete kit — includes high-clamp pressure plate, multi-puck carbon friction disc, high-torque solid hub and carrier assembly, bearing, and tool kit

Intended Use: Drag Racing, Drift, Road Race, Rallye, Pulling, Circle Track

Note: The Stage 4 is a race-only clutch. The rigid solid hub delivers instantaneous, aggressive engagement that is not suitable for street driving. The 6-puck configuration is the most street-tolerant option, but this kit is best suited for dedicated race and track applications.
