Spec Clutch SF233H-2 Stage 2 Plus Clutch Kit with Hybrid Kevlar Carbon Disc

The SPEC SF233H-2 Stage 2 Plus Clutch Kit is a high-performance clutch system engineered to bridge the gap between the Stage 2 and Stage 3 lineups. It delivers the smooth, streetable engagement feel of the Stage 2 while adding 15–20% more torque capacity — making it an ideal upgrade for enthusiasts who need more holding power without sacrificing daily drivability.

At the heart of the kit is a multi-friction disc in a full-face configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction pairing optimizes both grip and longevity across a wide range of operating conditions. The double-sprung hub features spring cover reliefs for added flexibility, while heat-treated internal components ensure long-term strength and durability under sustained high-load use.

Key Features:

• Hybrid friction disc — carbon semi-metallic and Kevlar full-face configuration for maximum torque transfer and wear resistance
• High-clamp pressure plate — engineered for increased clamping force over stock
• Double-sprung hub with spring cover reliefs for smooth engagement and drivetrain protection
• Heat-treated components for enhanced strength and durability
• Bearing and tool kit included for a complete installation package

Intended Use:

• Street
• Drag Racing
• Autocross
• Road Racing
• Pulling
• Rally
• Drift

The SPEC Stage 2 Plus is the go-to choice for performance drivers who have outgrown a standard Stage 2 clutch but want to preserve the predictable, street-friendly engagement that makes an aggressive clutch livable every day.
