Spec Clutch ST823 Stage 3 Performance Clutch Kit

The Spec Clutch ST823 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing everyday drivability. Designed to deliver aggressive yet streetable engagement, this kit strikes the ideal balance between performance and comfort, making it equally at home on the daily commute or at the track.

At the core of the Stage 3 kit is a carbon semi-metallic 6-puck sprung hub disc — the industry benchmark for puck clutch drivability, service life, and torque capacity. The hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated internal components provide the strength and durability needed under both low and high stress conditions. A 4-puck configuration can be specified at time of ordering on applicable fitments.

• High-clamp performance pressure plate
