Spec Clutch SF203H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SF203H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 kit can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit delivers the smooth, street-friendly engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — making it an ideal choice for enthusiasts who need more performance without sacrificing daily drivability.

At the core of the Stage 2 Plus is a multi-friction composite disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar® on the other. This hybrid friction material delivers excellent wear characteristics, consistent torque transfer, and reliable engagement across a wide range of driving conditions.

Key Features:

• High-clamp pressure plate for superior clamping force and torque holding capability
• Carbon semi-metallic / Kevlar® composite multi-friction disc in full-faced configuration for improved wear life and consistent engagement
• Double-sprung hub with spring cover reliefs for flexibility and smooth power delivery
• Heat-treated hub components for enhanced strength and long-term durability
• High-torque sprung hub and disc assembly engineered for demanding performance applications
• Bearing and installation tool kit included for a complete, ready-to-install package

Recommended Driving Styles: Street, Drag Racing, Road Racing, Rally, Pulling, Autocross

The SF203H is part of SPEC's American-made lineup of single-disc performance clutch kits, all designed and hand-built in the U.S.A. Flywheel must be resurfaced prior to installation unless using a new SPEC flywheel. A minimum 450-mile break-in period is required before full-throttle use.
