Spec Clutch SV364 Stage 4 Performance Clutch Kit

The Spec Clutch SV364 Stage 4 Clutch Kit is a high-performance racing clutch engineered for heavily modified engines demanding maximum torque capacity and instantaneous engagement. This kit is a solid hub evolution of the Stage 3 clutch, delivering the aggressive performance characteristics required for competitive motorsport applications.

Key Features:

• Solid 8-Rivet Hub: Heat-treated for exceptional strength and long-term durability under extreme loads
• High-Clamp Pressure Plate: Delivers increased clamping force to handle the demands of high-output, modified powerplants
• Multiple Puck Configurations: Available in 3, 4, or 6-puck carbon semi-metallic friction disc — choose 3-puck for the lightest possible rotating mass, 6-puck for the smoothest engagement, or 4-puck as an ideal compromise between the two
• Carbon Semi-Metallic Friction Material: Provides outstanding heat resistance and high torque capacity suited for racing environments
• High Torque Rigid Hub and Carrier Assembly: Designed for instantaneous, direct power transfer with zero flex
• Includes: Pressure plate, friction disc, release bearing, and installation tool kit

Ideal Motorsport Applications: Drag Racing, Drift, Road Racing, Rallye, Pulling, Circle Track

Important Notes: The Stage 4 is a race-only clutch and is not recommended for street use due to harsh, rigid hub engagement characteristics. Street drivability is possible in the 6-puck configuration but is not advised for daily driving. A new or properly resurfaced flywheel is required for installation. A minimum 450-mile break-in period of city and stop-and-go driving is required before full-throttle launches or speed shifting.
