Spec Clutch SN054 Stage 4 Race Clutch Kit - Carbon Semi-Metallic Puck Disc

The SPEC SN054 Stage 4 Clutch Kit is a race-grade clutch system engineered for heavily modified engines where maximum torque transfer, instantaneous engagement, and reduced rotating mass are the priority. Rated to handle up to 307 ft-lbs of torque, this kit is purpose-built for competitive motorsport applications including drag racing, road racing, drifting, rallye, and pulling.

Key Features:

• Solid 8-rivet rigid hub — a solid hub evolution of the Stage 3, heat-treated for superior strength and durability under sustained high-load conditions
• High-clamp pressure plate — delivers aggressive, precise clutch engagement and maximizes clamping force for high-torque applications
• Carbon semi-metallic friction material — engineered to withstand extreme heat and friction generated during competitive driving
• Available in 3, 4, or 6-puck configurations — choose 3-puck for the lightest setup, 6-puck for the smoothest engagement, or 4-puck as a balanced compromise
• Complete kit — includes high-clamp pressure plate, puck-style clutch disc with rigid carrier assembly, release bearing, and installation tool kit

Intended Use:

• Drag Racing
• Road Racing
• Drift
• Rallye
• Pulling
• Circle Track

Important Note: Due to the solid rigid hub design, this clutch is not recommended for street use. The Stage 4 engages instantaneously with no dampening, making it unsuitable for daily driving but ideal for dedicated race builds requiring maximum performance and reliability at the limit.
