Spec Clutch SF333 Stage 3 Performance Clutch Kit

The SPEC SF333 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand maximum performance without sacrificing daily usability. Despite its high-performance design, the Stage 3 delivers a comfortable pedal feel with quick, responsive engagement — making it a practical upgrade for drivers who push their vehicles hard on and off the track.

Built around a high-clamp pressure plate, the SF333 uses a 4 or 6 puck carbon semi-metallic friction disc paired with a high-torque sprung hub and disc assembly. The 6 puck configuration is standard on most applications, while the 4 puck disc can be specified at time of ordering. The kit includes the clutch disc, pressure plate, release bearing, and installation tool kit — everything needed for a complete clutch replacement.

Key Features:

• High-clamp pressure plate for maximum torque holding capacity
• Carbon semi-metallic 4 or 6 puck friction disc (6 puck standard)
• High-torque sprung hub and disc assembly for smooth power transfer
• Excellent wear characteristics under both low and high stress conditions
• Comfortable pedal feel with quick engagement for street and race use
• Complete kit includes disc, pressure plate, release bearing, and installation tool

Intended Use: Street, Drag Racing, Drift, Road Racing, Rallye, Pulling, Autocross

The SPEC Stage 3 is the ideal choice for enthusiasts and competitors who need a clutch that can handle aggressive power levels while remaining livable for everyday driving.
