Spec Clutch SV234-2 Stage 4 Carbon-Graphite Clutch Kit

The SPEC SV234-2 Stage 4 Clutch Kit is a race-grade, solid hub clutch designed for drivers who demand maximum torque capacity and durability under extreme conditions. Built as the solid hub evolution of the Stage 3, this kit is rated to handle up to 517 ft-lbs of torque and is engineered for competition use in drag racing, road racing, rally, drifting, and pulling applications.

The Stage 4 features a solid 8-rivet hub with a heat-treated disc assembly for exceptional strength and resistance to high-stress driving conditions. Unlike sprung-hub designs, the rigid solid hub maximizes power transfer, making this kit best suited for dedicated performance and race builds.

Puck Configuration Options:

• 3-Puck: Lightest option, ideal for weight-sensitive race applications
• 4-Puck: A balanced compromise between weight savings and engagement smoothness
• 6-Puck: Smoothest engagement of the three; street-drivable but not street-friendly due to the rigid hub

Key Features:

• High-clamp performance pressure plate for increased torque holding capacity
• Carbon-graphite friction material for high heat resistance and consistent bite
• Solid 8-rivet, heat-treated hub and disc assembly for maximum durability
• Available in 3, 4, or 6-puck disc configurations
• Includes bearing and tool kit
• Flywheel not included

Recommended Applications: Drag racing, road racing, rally, drifting, and pulling. Not recommended as a daily street clutch due to the rigid hub design.
