SPEC SM663H Stage 2+ Clutch Kit with Carbon-Kevlar Disc

The SPEC SM663H Stage 2+ Clutch Kit is engineered for modified and high-performance engines that have exceeded the torque capacity of the standard Stage 2 clutch. Combining increased holding power with familiar street-friendly engagement, this kit delivers the ideal balance of performance and everyday drivability.

At the heart of the SM663H is a composite multi-friction carbon-kevlar disc paired with a high-clamp pressure plate, offering superior torque capacity over the standard Stage 2 while preserving the progressive, smooth pedal feel drivers expect. The included high-torque sprung hub and disc assembly helps dampen drivetrain shock and extend the life of transmission components.

Key Features:

• High-clamp pressure plate for increased torque holding capacity beyond Stage 2
• Composite multi-friction carbon-kevlar friction disc for excellent wear characteristics
• High-torque sprung hub and disc assembly for smooth power transfer and drivetrain protection
• Retains Stage 2 pedal feel for comfortable daily driving
• Complete kit includes clutch disc, pressure plate, release bearing, and installation tool kit
• Suitable for street, drag racing, road racing, rally, pulling, and autocross applications

The SPEC SM663H Stage 2+ is an excellent choice for turbocharged, supercharged, or otherwise modified vehicles that demand more than a stock-replacement clutch can provide, without sacrificing the comfort and longevity needed for regular street use.
