SPEC SN343F Stage 3+ High-Performance Clutch Kit

The SPEC Stage 3+ (SN343F) clutch kit is the flagship performance stage for heavily modified street and race engines that have exceeded the torque capacity of a standard Stage 3. Engineered as the top-tier single-disc solution in the SPEC lineup, it delivers the high torque handling of a race clutch while maintaining a more manageable and streetable engagement feel than an outright race-only kit.

At the heart of this kit is a carbon semi-metallic full-face friction disc, a material chosen for its exceptional combination of longevity, friction coefficient, and daily drivability. The disc rides on a high-torque double-sprung hub with spring cover reliefs for added flexibility, and heat-treated components throughout for superior strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Full-face carbon semi-metallic friction disc
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Recommended Driving Applications:

• Street performance
• Drag racing
• Drifting
• Road racing
• Rallye
• Autocross
• Pulling

Installation Note: Unless using a new SPEC flywheel, the existing flywheel must be resurfaced prior to installation to ensure proper friction surface integrity.
