Spec Clutch SN234 Stage 4 Performance Clutch Kit

The Spec Clutch SN234 Stage 4 Clutch Kit is a race-focused clutch system engineered for heavily modified engines demanding maximum torque capacity, instantaneous engagement, and reduced rotating mass. Built as a solid-hub evolution of the Stage 3, this kit is purpose-built for motorsport applications where holding power and response take priority over street comfort.

Key Features:

• High-clamp pressure plate for superior clamping force on high-horsepower builds
• Carbon semi-metallic friction disc available in 3, 4, or 6-puck configuration — choose 3-puck for the lightest rotating mass, 6-puck for the smoothest engagement, or 4-puck as a balanced compromise
• Solid 8-rivet rigid hub with heat-treated carrier assembly for exceptional strength and durability under race conditions
• Includes release bearing and installation tool kit for a complete, ready-to-install package
• Designed and hand-built in the USA

Intended Use:

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

Note: The Stage 4 features a rigid hub design, which produces harsh, abrupt engagement characteristics. It is streetable in the 6-puck configuration but is not recommended for daily street driving. Best suited for dedicated race and competition builds.
