Spec Clutch SA593F Stage 3 Plus Performance Clutch Kit

The SPEC SA593F Stage 3 Plus Clutch Kit is the flagship performance clutch solution engineered for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can support. It delivers a winning combination of high torque handling and surprisingly manageable daily drivability — making it ideal for drivers who push their vehicles hard without sacrificing street usability.

At the heart of this kit is a carbon semi-metallic full-faced friction disc that provides outstanding friction coefficient, exceptional wear life, and consistent engagement characteristics in a single package. The double-sprung hub features spring cover reliefs for added flexibility and heat-treated components for long-term strength and durability under extreme conditions.

Designed, hand-built, and tested in the U.S.A., the SPEC Stage 3 Plus represents the pinnacle of single-disc clutch performance — offering superior wear characteristics and better overall manageability than the Stage 3, without sacrificing the high-torque capacity serious motorsport demands.
