Spec Clutch SC863H Stage 2 Plus Performance Clutch Kit

The SPEC SC863H 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, this kit delivers 15–20% higher torque capacity while preserving the familiar, street-friendly engagement feel of the Stage 2 — making it an ideal upgrade for high-performance builds that still see daily use.

The Stage 2 Plus uses a multi-friction disc in a full-face configuration, combining carbon semi-metallic material on one side and Kevlar® on the other for excellent wear resistance and consistent torque transfer across a wide range of driving conditions. The hub is double-sprung with spring cover reliefs for smooth, flexible engagement, and all hub components are heat-treated for long-term strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Multi-friction composite disc — carbon semi-metallic / Kevlar® full-face configuration
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Recommended Driving Applications:

• Street / Daily Driving
• Drag Racing
• Road Racing
• Rally

All SPEC clutch kits are designed, hand-built, and tested in the USA, delivering race-proven performance with the quality and precision that modified vehicle owners demand.
