Spec Clutch ST693H Stage 2 Plus Performance Clutch Kit

The Spec Clutch ST693H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit provides 15–20% higher torque capacity while retaining the smooth, street-friendly engagement feel of the Stage 2 — making it an ideal choice for high-performance builds that still see regular street use.

The disc features a full-faced, multi-friction design with carbon semi-metallic material on one side and Kevlar® on the other, delivering a combination of aggressive grip, heat resistance, and excellent wear life. The hub is double-sprung with spring cover reliefs for added flexibility, and heat-treated internal components provide long-term strength and durability under high-load conditions.

Kit Includes:

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

Intended Use:

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

Designed, hand-built, and tested in the U.S.A., the Spec ST693H Stage 2 Plus delivers race-proven performance with the day-to-day drivability that modified street cars require.
