Spec Clutch SZ453 Stage 3 Performance Clutch Kit

The Spec Clutch SZ453 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing daily drivability. It delivers a comfortable pedal feel, quick engagement, and strong wear characteristics under both low and high stress conditions.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — widely recognized as the leading puck clutch design for its balance of drivability, service life, and torque capacity. The disc hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated components provide long-term strength and durability. A high-clamp pressure plate rounds out the assembly, delivering the clamping force needed for high-output applications. A 4-puck configuration is also available and can be specified at the time of ordering.

• High-clamp performance pressure plate

Every SPEC clutch kit is SFI approved and manufactured to precise tolerances for consistent, reliable performance.
