Spec Clutch SF372 Stage 2 Kevlar Clutch Kit - Street/Strip

The Spec Clutch SF372 Stage 2 Clutch Kit is engineered for drivers who demand more than a stock clutch can offer without sacrificing everyday drivability. Featuring a pure Kevlar friction disc with steel backing, this kit delivers outstanding wear resistance and a smooth, progressive engagement feel — ideal for street driving, spirited weekend use, drag racing, autocross, and pulling applications.

The Stage 2 is the ideal step up for mild to moderately modified naturally aspirated and power-adder equipped engines, with a torque capacity rating of up to 270 ft-lbs. It retains stock-like pedal feel, making it equally well-suited for daily-driven vehicles where long clutch life and predictable engagement are priorities.

Kit Includes:

• High-clamp performance pressure plate
• Pure Kevlar friction disc with steel backing and sprung hub assembly
• Release (throwout) bearing
• Clutch alignment tool

Key Features:

• Segmented or full-faced Kevlar disc construction for excellent durability and drivability
• High-torque sprung hub and disc assembly for smooth power transfer
• Higher torque capacity and longer service life compared to Stage 1
• Suitable for street, drag, autocross, and pulling use
• Stock-like engagement feel — no aggressive on/off behavior

Installation Note: If reusing an existing flywheel, it must be resurfaced prior to installation. A minimum 500-mile break-in period of primarily city and stop-and-go driving is required before full-throttle launches or power shifting.
