Spec Clutch SO112 Stage 2 Performance Clutch Kit - Kevlar Full Face Disc

The Spec Clutch SO112 Stage 2 Clutch Kit delivers the ideal balance of street drivability and performance-grade holding power. Engineered for mild to moderately modified naturally aspirated and power-adder engines, this kit is equally well-suited for stock power levels where exceptional longevity and smooth daily drivability are the priority.

Key Features:

• Full-face or segmented pure Kevlar® friction disc with steel backing for superior wear resistance and high torque capacity
• High-clamp pressure plate for increased clamping force over OEM spec
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement and heat-treated components for long-term durability
• 9.000 in. (229mm) disc diameter with 20-spline input shaft interface (0.850 in. diameter)
• Bearing and alignment tool kit included
• Single clutch disc configuration — flywheel not included

The Stage 2 Kevlar® lining delivers stock-like engagement feel with excellent daily drivability, while providing slightly greater torque capacity and longer service life compared to a Stage 1 setup. Suitable for street, drag, autocross, and pulling applications. All Spec clutch components are designed, hand-built, and tested in the U.S.A.
