Spec Clutch SF273HCJ Stage 2 Plus Performance Clutch Kit

The SPEC SF273HCJ Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 setup can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit maintains the smooth, street-friendly engagement feel of the Stage 2 while delivering 15–20% higher torque capacity — making it ideal for high-performance builds that still see regular street use.

At the core of the Stage 2 Plus is a composite multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar® on the other. This hybrid construction delivers excellent wear characteristics, consistent engagement, and the durability needed for demanding driving conditions. The hub is double-sprung with spring cover reliefs for added flexibility, and all hub components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Full-faced composite disc: carbon semi-metallic on one side, Kevlar® on the other
• Double-sprung hub with spring cover reliefs for pedal feel and flexibility
• Heat-treated hub components for strength and durability
• High-torque sprung hub and disc assembly
• Bearing and installation tool kit included

Intended Use: Street, Drag Racing, Road Racing, Rally, Pulling, Autocross

The SPEC Stage 2 Plus clutch kit is the ideal choice for enthusiasts with modified engines who need more capability than a Stage 2 offers, without sacrificing the daily drivability that a Stage 3 can compromise.
