Spec Clutch ST772 Stage 2 Kevlar Clutch Kit

The Spec Clutch ST772 Stage 2 Clutch Kit is a high-performance upgrade engineered for drivers who demand more holding power without sacrificing everyday drivability. Ideal for mild to moderately modified naturally aspirated and power-adder engines, the Stage 2 is also an excellent choice for stock power levels where long service life and smooth street manners are the priority.

At the heart of this kit is a segmented or full-faced pure Kevlar friction disc with a steel backing. This friction material delivers the same smooth, predictable engagement feel as a Stage 1, while providing a meaningful step up in torque capacity and disc longevity — making it the go-to choice for enthusiasts who spend time on both the street and the strip.

Key Features:

• Pure Kevlar friction disc with steel backing for excellent wear resistance and torque capacity
• High-clamp pressure plate for increased clamping force over stock
• High-torque sprung hub and disc assembly for smooth, street-friendly engagement
• Alignment tool and bearing included for straightforward installation
• SFI approved — manufactured under strict tolerances
• Suitable for street, drag racing, autocross, and pulling applications

Installation Note: Unless using a new SPEC flywheel, the existing flywheel must be resurfaced prior to installation. A minimum 450-mile break-in period of primarily city and stop-and-go driving is required before full-throttle engagement or speed shifting.

The SPEC ST772 Stage 2 strikes the ideal balance between performance and drivability, making it a proven upgrade for enthusiasts who refuse to compromise at the track or on the commute home.
