Spec Clutch SD843 Stage 3+ Performance Clutch Kit

The Spec Clutch Stage 3+ is engineered for heavily modified street and race engines that demand superior torque capacity while maintaining street drivability. This performance clutch kit bridges the gap between aggressive street use and full competition applications, offering a manageable pedal feel with quick, positive engagement.

Kit Includes:

• High clamp pressure plate for increased torque capacity
• Carbon semi-metallic friction disc (4 or 6 puck configuration)
• High torque sprung hub and disc assembly to reduce drivetrain shock
• Release bearing
• Alignment tool

Performance Features:

• Carbon semi-metallic friction material provides excellent heat dissipation and wear resistance
• Sprung hub design dampens vibration and protects transmission components
• Capable of handling 30-50% increase in torque over stock
• Good wear characteristics under both low and high stress conditions
• Suitable for daily driving with upgraded power levels

Recommended Applications: Street performance, drag racing, drifting, road racing, rally, pulling, and autocross. The Stage 3+ configuration is ideal for turbocharged, supercharged, or heavily built naturally aspirated engines that see both street and track duty.

Note: 6-puck disc is standard on most applications. 4-puck configuration available upon request for specific fitments requiring reduced rotational mass.
