Spec Clutch SB343F Stage 3 Plus Clutch Kit

The SPEC SB343F Stage 3 Plus Clutch Kit is the flagship performance clutch solution for heavily modified street and race engines that demand more torque capacity than the standard Stage 3 can handle. Engineered for high-powered builds that still require daily drivability, the Stage 3+ delivers superior manageability and engagement feel compared to more aggressive race-only clutches, while offering exceptional wear characteristics for long service life.

At the heart of the Stage 3+ is a carbon semi-metallic full-faced friction disc that provides an outstanding balance of torque capacity, friction coefficient, and street-friendly drivability in a single package. The double-sprung hub features spring cover reliefs for added flexibility, with heat-treated components throughout for enhanced strength and durability under extreme loads.

Kit Includes:

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

Intended Use:

• Street driving (daily drivability)
• Drag racing

• Road racing
• Autocross

The SPEC Stage 3 Plus is the ideal choice for enthusiasts who need maximum torque capacity without sacrificing the street manners required for everyday use.
