Spec Clutch SA173 Stage 3 Performance Clutch Kit

The Spec Clutch SA173 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing daily drivability. Featuring a comfortable pedal feel and quick, positive engagement, the Stage 3 strikes the ideal balance between aggressive performance and street-friendly usability.

At the heart of this kit is a carbon semi-metallic puck disc — available in a 4-puck or 6-puck configuration (6-puck is standard on most applications; 4-puck available upon request) — mounted on a high-torque sprung hub assembly. The sprung hub is double-wound for added flexibility, with heat-treated components for long-term strength and durability under both low and high stress conditions.
