Spec Clutch SN623 Stage 3 Performance Clutch Kit Carbon Semi-Metallic 6-Puck

The SPEC SN623 Stage 3 Clutch Kit is engineered for heavily modified street and competition vehicles that demand aggressive grip without sacrificing daily drivability. Rated for up to 357 ft-lbs of torque, this kit strikes the ideal balance between streetable engagement and high-performance holding power, making it a top choice for street/strip builds across a wide range of driving disciplines.

At the heart of the Stage 3 kit is a carbon semi-metallic 6-puck sprung hub disc — SPEC's most proven puck-style clutch design, delivering exceptional drivability, service life, and torque capacity. The high-clamp pressure plate works in tandem with the high-torque disc assembly to provide firm, confidence-inspiring engagement under both daily driving and wide-open-throttle conditions. A 4-puck configuration can be specified for certain applications where required.
