Spec Clutch ST693 Stage 3 Performance Clutch Kit

The Spec Clutch ST693 Stage 3 Clutch Kit is the ultimate street/strip solution for heavily modified street and race engines that demand high torque capacity without sacrificing everyday drivability. Engineered for drivers who push their vehicles hard on the street and at the track, this kit delivers sharp, confident engagement with a comfortable pedal feel that remains manageable in daily driving conditions.

At the heart of the Stage 3 is a carbon semi-metallic puck disc — available in 4 or 6 puck configurations (6 puck is standard on most applications; 4 puck can be specified at the time of ordering). The sprung hub design is double-sprung with spring cover reliefs for added flexibility, while heat-treated components provide the strength and durability needed to survive repeated high-stress use. A high-clamp pressure plate ensures maximum clamping force under load, and the complete kit includes a bearing and tool kit for straightforward installation.
