Spec Clutch SC413 Stage 3 Carbon Semi-Metallic Clutch Kit

The Spec Clutch SC413 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand serious torque capacity without sacrificing everyday drivability. This kit strikes the ideal balance between race-ready performance and a comfortable, manageable pedal feel — making it a top choice for high-output builds that see both street and competition use.

At the heart of the Stage 3 is a carbon semi-metallic puck disc paired with a high-clamp pressure plate, delivering exceptional bite, quick engagement, and outstanding wear characteristics under both low and high-stress conditions. The sprung hub design absorbs drivetrain shock for smoother daily driving while still holding up to demanding track sessions.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic puck friction disc — 6-puck standard (4-puck available upon request)
• Sprung hub disc assembly for drivability and shock absorption
• Throwout bearing
• Alignment tool

Intended Use:

• Street performance
• Drag racing
• Drifting
• Road racing
• Rallye
• Pulling
• Autocross

The SPEC Stage 3 is SFI approved and part of a complete clutch lineup ranging from Stage 1 street kits through Stage 5 full-race units. It is the preferred choice for modified engines that need a reliable, high-torque clutch solution with real-world drivability.
