Spec Clutch SM063H Stage 2 Plus Clutch Kit - Carbon-Kevlar Multi-Friction

The SPEC SM063H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle. Bridging the gap between the Stage 2 and Stage 3, the Stage 2 Plus delivers the same smooth daily-drivability and forgiving engagement feel of the Stage 2 while offering a 15–20% higher torque capacity — making it the ideal upgrade for street-driven performance builds that also see track duty.

The disc features a composite multi-friction design in a full-faced configuration, with carbon semi-metallic material on one side and Kevlar® on the other. This hybrid construction provides excellent wear characteristics, strong heat resistance, and consistent engagement across a wide range of operating conditions. The double-sprung hub with spring cover reliefs adds flexibility while heat-treated internal components ensure long-term strength and durability under high-torque loads.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Composite multi-friction disc — carbon semi-metallic on one side, Kevlar® on the other
• Full-faced disc configuration for smooth, progressive engagement
• Double-sprung hub with spring cover reliefs for flexibility and vibration damping
• Heat-treated components for enhanced strength and durability
• Includes release bearing and installation tool kit

Ideal Driving Applications: Street, Drag Racing, Road Racing, Rally, Autocross, Pulling, and Drifting
