Spec Clutch SC683 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic Puck Disc

The Spec Clutch SC683 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing daily drivability. Designed for aggressive yet streetable engagement, this kit delivers a comfortable pedal feel, quick engagement, and strong wear characteristics under both low and high stress conditions.

At the heart of the Stage 3 kit is a carbon semi-metallic puck disc — available in 4 or 6 puck configurations depending on the application (6 puck is standard on most fitments, with 4 puck available upon request). The disc features a double-sprung hub with spring cover reliefs for improved flexibility, and heat-treated components for long-term strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• 4 or 6 puck carbon semi-metallic friction disc (application dependent)
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Ideal Driving Applications:

• Street / Daily Driving
• Drag Racing
• Drifting
• Road Racing
• Rallye

• Autocross

All Spec Clutch products are designed, hand-built, and tested in the USA, using advanced friction materials and race-proven engineering. The Stage 3 sits in SPEC's single-disc lineup between Stage 2+ and Stage 3+, making it the ideal step up for performance builds that still see regular street use.
