Spec Clutch SN463F Stage 3 Plus Performance Clutch Kit

The Spec Clutch SN463F Stage 3+ Clutch Kit is the flagship performance clutch solution for heavily modified street cars and race vehicles demanding maximum torque capacity with a manageable, street-friendly engagement. Built for high-powered applications that exceed what the Stage 3 can handle, the Stage 3+ delivers the ideal balance of aggressive holding power and daily drivability in a single package.

At the heart of this kit is a full-faced carbon semi-metallic friction disc, engineered to provide exceptional friction coefficient, extended wear life, and smooth engagement characteristics. The sprung hub is double-sprung with spring cover reliefs, adding flexibility during engagement while heat-treated internal components ensure long-term strength and durability under high-load conditions.

Kit Includes:

• High-clamp pressure plate for maximum clamping force
• Full-faced carbon semi-metallic friction disc
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Intended Driving Applications:

• Street

All Spec clutch kits are designed, hand-built, and tested in the U.S.A. A proper break-in period of at least 450 miles of primarily city and stop-and-go driving is recommended before full-throttle or performance use. For best results, resurface or replace the flywheel prior to installation.
