Spec Clutch SS204 Stage 4 Performance Clutch Kit

The SPEC SS204 Stage 4 Clutch Kit is engineered for heavily modified, high-output engines where maximum torque capacity, instantaneous engagement, and reduced rotating mass are the priority. This is a dedicated competition clutch — not intended for street use — and is purpose-built for drivers who demand uncompromising performance on the track.

Key Features:

• High-clamp pressure plate designed to handle significantly elevated torque loads beyond stock specifications
• Carbon semi-metallic friction disc available in 3-puck, 4-puck, or 6-puck configurations for tunable engagement characteristics
• Solid 8-rivet rigid hub — a solid hub version of the Stage 3 design, heat-treated for enhanced strength and durability
• High-torque rigid hub and carrier assembly eliminates flex for direct, immediate power transfer
• Includes release bearing and installation tool kit for a complete installation package
• Designed, hand-built, and tested in the U.S.A.

Recommended Driving Applications: Drag Racing, Drifting, Road Racing, Rallye, Pulling, Circle Track

Note: Due to the aggressive engagement characteristics of the carbon semi-metallic puck disc and solid hub design, this clutch kit is not recommended for street use. It is intended exclusively for competition and track applications where harsh, instantaneous engagement is desirable and expected.
