Spec Clutch SH223F Stage 3 Plus Performance Clutch Kit

The Spec Clutch SH223F Stage 3 Plus is the flagship high-performance clutch kit designed for heavily modified street machines and dedicated race cars that demand maximum torque capacity with a manageable, street-friendly engagement. Rated at 315 ft-lbs of torque capacity, this kit goes beyond what the standard Stage 3 can handle while still delivering superior daily drivability and better wear characteristics than more aggressive race-only clutch stages.

At the heart of the Stage 3 Plus is a full-faced carbon semi-metallic friction disc — a material that delivers an outstanding balance of friction coefficient, service life, and engagement quality in a single package. Unlike the puck-style Stage 3 disc, the full-faced design provides smoother, more consistent engagement across the clutch surface, making it an ideal choice for drivers who need race-level torque handling without sacrificing street manners.

Kit Includes:

• High-clamp performance pressure plate
• Full-faced carbon semi-metallic friction disc
• High-torque double-sprung hub and disc assembly
• Sprung hub with spring cover reliefs for flexibility and heat-treated components for durability
• Release bearing and installation tool kit

Ideal Driving Applications:

• Street / High-Performance Street
• Drag Racing
• Drifting
• Road Racing
• Autocross
• Rallye
• Pulling

The double-sprung hub design absorbs drivetrain shock and reduces wear on transmission components, making this clutch a strong long-term investment for performance builds. Whether you're building a track-day weapon or a high-powered daily driver, the SPEC SH223F Stage 3 Plus delivers race-proven performance with an engagement feel you can actually live with.
