Spec Clutch SN422 Stage 2 Performance Clutch Kit with Kevlar Disc

The Spec Clutch SN422 Stage 2 Clutch Kit is an ideal upgrade for mild to moderately modified naturally aspirated and power-adder engines. It also excels at stock power levels when long service life and smooth daily drivability are the priority — delivering a confident, street-friendly feel without sacrificing durability.

The Stage 2 builds on the drivability of the Stage 1 by incorporating a pure Kevlar friction disc with steel backing, delivering slightly greater torque capacity and longer service life. The high-clamp pressure plate and high-torque sprung hub work together to handle increased power demands while maintaining the smooth, predictable engagement expected from a daily driver.

Kit Includes:

• High-clamp performance pressure plate
• Segmented or full-faced pure Kevlar friction disc with steel backing
• High-torque sprung hub and disc assembly
• Release bearing
• Alignment tool

Recommended Driving Applications:

• Street
• Drag Racing
• Pulling
• Autocross

Spec Clutch engineers each Stage 2 kit to provide the optimal balance of holding power and everyday drivability, making the SN422 a smart choice for performance builds that spend as much time on the street as they do at the track.
