Spec Clutch SZ363 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch SZ363 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand aggressive performance without sacrificing daily drivability. Designed for drivers who need high torque capacity with a comfortable pedal feel and quick, consistent engagement, the Stage 3 is the go-to upgrade for serious street/strip builds.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — SPEC's proven leader in puck clutch drivability, service life, and torque capacity. The double-sprung hub features spring cover reliefs for added flexibility, while heat-treated components deliver long-lasting strength under both daily and high-stress conditions. A high-clamp pressure plate rounds out the assembly for reliable, firm engagement. Note: a 4-puck configuration can be specified at the time of ordering on select applications.
