Spec Clutch SC803 Stage 3 Performance Clutch Kit

The SPEC Stage 3 Clutch Kit (SC803) is engineered for heavily modified street and race engines that demand serious performance. Designed to handle high-torque applications while retaining acceptable daily drivability, the Stage 3 delivers a comfortable pedal feel and quick, positive engagement — making it a versatile choice for both spirited street driving and competitive motorsport use.

At the heart of the kit is a high-clamp pressure plate paired with a 4 or 6-puck carbon semi-metallic friction disc featuring a high-torque sprung hub assembly. The sprung hub design helps absorb driveline shock and reduces noise, while the carbon semi-metallic puck material delivers excellent bite and impressive wear characteristics under both low and high stress conditions. The 6-puck disc configuration is standard on most applications; a 4-puck disc can be specified at the time of ordering for specific fitment needs.

Kit Includes:

• High-clamp performance pressure plate
• 4 or 6-puck carbon semi-metallic friction disc with high-torque sprung hub
• Clutch disc assembly
• Release bearing
• Installation tool kit

Intended Driving Applications:

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

The SPEC Stage 3 is the ideal upgrade for drivers who have outgrown stock and Stage 1/Stage 2 clutch setups and need a reliable, high-performance clutch system that can keep pace with significant engine modifications.
