Spec Clutch SO123F Stage 3+ Clutch Kit with Carbon Metallic Disc

The SPEC Stage 3+ Clutch Kit (SO123F) is engineered for heavily modified street machines and dedicated race vehicles that demand torque capacity beyond what the standard Stage 3 can deliver. Designed with improved daily drivability and enhanced manageability over the Stage 3, the Stage 3+ also offers superior wear characteristics, making it an ideal choice for high-output builds that see regular street use alongside demanding track or strip duty.

At the heart of this kit is a high-clamp pressure plate paired with a full-faced carbon metallic friction disc, a combination that provides aggressive clamping force while maintaining smooth engagement. The high-torque sprung hub and disc assembly absorbs driveline shock, reducing wear on transmission and drivetrain components. Everything needed for installation is included right in the box.

Key Features:

• High-clamp pressure plate for maximum torque holding capacity
• Full-faced carbon metallic friction disc for aggressive grip and extended wear life
• High-torque sprung hub and disc assembly for driveline shock absorption
• Release bearing and installation tool kit included
• Improved drivability and manageability compared to Stage 3
• Superior wear characteristics for longer service intervals

Intended Use:

• Street
• Drag Racing
• Drifting
• Road Racing
• Pulling

The SPEC SO123F Stage 3+ Clutch Kit is the go-to upgrade for drivers who have outgrown the Stage 3 but still want a clutch system that remains manageable and livable on the street without sacrificing race-level performance.
