Spec Clutch SM493 Stage 3 Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch SM493 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand high torque capacity without sacrificing daily drivability. Featuring an aggressive yet streetable engagement profile, this kit delivers confident pedal feel and excellent wear characteristics under both routine and high-stress driving conditions.

At the heart of the Stage 3 kit is a carbon semi-metallic 6-puck sprung hub disc — long regarded as the benchmark puck clutch for its balance of drivability, service life, and torque capacity. The hub is double-sprung with spring cover reliefs for drivetrain flexibility, and all load-bearing components are heat-treated for strength and long-term durability. A high-clamp pressure plate provides the firm clamping force needed for high-output applications. A 4-puck disc configuration is also available when ordering for specific application requirements.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic 4 or 6-puck sprung hub disc assembly (6-puck standard on most applications)
• High-torque sprung hub assembly
• Release bearing
• Installation tool kit

Intended Driving Applications:

• Street / Daily Driven
• Drag Racing
• Drifting
• Road Racing
• Rallye
• Pulling
• Autocross

The Spec SM493 Stage 3 is the ideal upgrade for drivers who need a clutch that can handle serious power while remaining manageable on the street. As with all Spec performance clutch kits, a proper break-in period is recommended to ensure optimal friction surface seating and long service life.
