Spec Clutch ST703 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch ST703 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing daily drivability. It delivers an aggressive yet streetable engagement feel, making it a versatile choice across a wide range of performance driving applications including street, drag, drift, road racing, rallye, pulling, and autocross.

At the core of the Stage 3 kit is a carbon semi-metallic 6-puck sprung hub disc — widely regarded as the leading puck clutch in drivability, service life, and torque capacity. The disc hub is double-sprung with spring cover reliefs for enhanced flex and heat-treated internal components for maximum strength and long-term durability under both street and high-stress race conditions.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic friction disc (6-puck standard; 4-puck available by request)
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Driving Applications:

• Street Performance
• Drag Racing
• Drifting
• Road Racing
• Rallye

• Autocross

The Spec Stage 3 is the ideal step up for drivers who need race-capable clutch performance with enough comfort for regular street use. Note: 6-puck configuration is standard on most applications; 4-puck disc can be specified at time of ordering. Some applications may utilize a solid hub depending on flywheel setup.
