Spec Clutch SO422 Stage 2 Clutch Kit with Kevlar Disc and High Clamp Pressure Plate

The Spec Clutch SO422 Stage 2 Clutch Kit is engineered for mild to moderately modified naturally aspirated and power-adder engines, while also delivering outstanding results at stock power levels. Designed with street drivability as a priority, this kit is an ideal choice for enthusiasts who demand both performance and long-term reliability from their daily driver.

At the heart of the Stage 2 kit is a segmented or full-faced pure Kevlar friction disc with a steel backing plate. This friction material delivers smooth, predictable engagement characteristics comparable to a stock clutch, while providing improved torque capacity and extended service life over a standard Stage 1 setup. The high clamp pressure plate ensures a firm, positive lockup under demanding conditions without sacrificing everyday drivability.

Key Features:

• Pure Kevlar friction disc — segmented or full-faced configuration with steel backing for strength under high clamp loads and elevated temperatures
• High clamp pressure plate for increased torque holding capacity
• High-torque sprung hub and disc assembly for smooth engagement and vibration damping
• Includes throwout bearing and installation tool kit
• Excellent wear characteristics for long service life
• Stock-like daily drivability — no harsh engagement or chatter

Recommended Driving Applications: Street, Drag Racing, Pulling, Autocross

The Spec SO422 Stage 2 kit is a complete, ready-to-install clutch solution for drivers looking to step up their drivetrain's torque capacity without sacrificing the comfort and ease of a street-friendly clutch feel.
