Spec Clutch SE603H Stage 2 Plus Performance Clutch Kit

The SPEC SE603H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle. It bridges the gap between Stage 2 drivability and Stage 3 holding power, making it an ideal choice for high-performance street builds as well as competitive motorsport applications.

At the heart of the Stage 2 Plus is a composite multi-friction disc in a full-faced configuration, featuring carbon semi-metallic material on one side and carbon-Kevlar on the other. This dual-material design delivers a 15–20% higher torque capacity over the Stage 2 while preserving the smooth, predictable engagement feel that makes the Stage 2 so well-regarded for daily drivability and long wear life.

Kit Includes:

• High-clamp performance pressure plate
• Composite multi-friction carbon-Kevlar clutch disc
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Intended Use:

• Street
• Drag Racing
• Road Racing
• Rally
• Pulling
• Autocross

SPEC clutch kits are designed, hand-built, and tested in the U.S.A., and each kit is engineered using advanced friction materials and race-proven designs to ensure consistent performance in every driving condition.
