Spec Clutch SD763 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch SD763 Stage 3 Clutch Kit is engineered for heavily modified street and race vehicles that demand serious torque capacity without sacrificing daily drivability. Designed for aggressive yet streetable engagement, this kit delivers a comfortable pedal feel, quick engagement, and excellent wear characteristics under both low and high-stress driving conditions.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — the leading puck clutch design in its class for drivability, service life, and torque capacity. The hub features a double-sprung design with spring cover reliefs for drivetrain flexibility, paired with heat-treated components for long-term strength and durability. A high-clamp pressure plate rounds out the assembly, maximizing clamping force for high-power applications.
