Spec Clutch SF963H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SF963H Stage 2 Plus Clutch Kit is the ideal upgrade for modified engines that have outgrown the torque capacity of a standard Stage 2 clutch but don't require the full aggression of a Stage 3. Bridging the gap between the two stages, the Stage 2 Plus delivers a 15–20% higher torque capacity than the Stage 2 while retaining the smooth, streetable engagement feel that makes daily driving comfortable.

The friction disc uses a full-faced, multi-friction hybrid design — carbon semi-metallic material on one side and Kevlar on the other — providing excellent grip, controlled engagement, and strong wear resistance across a wide range of driving conditions. The hub is double-sprung with spring cover reliefs for added flexibility, and all internal components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp performance pressure plate for increased clamping force
• Hybrid multi-friction disc: carbon semi-metallic on one side, Kevlar on the other
• Full-faced disc configuration for consistent engagement and wear
• Double-sprung hub with spring cover reliefs for flexibility
