Spec Clutch SO703H Stage 2 Plus Performance Clutch Kit

The SPEC SO703H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 kit can handle. Bridging the gap between the Stage 2 and Stage 3, the Stage 2 Plus delivers the familiar, street-friendly feel of the Stage 2 while providing a 15–20% higher torque capacity — making it the ideal step up for performance-tuned vehicles.

The kit features a multi-friction disc in a full-faced configuration, with carbon semi-metallic material on one side and Kevlar on the other. This composite design delivers excellent drivability and engagement quality while offering outstanding wear characteristics for both street and competition use. The high-clamp pressure plate maximizes holding power, and the double-sprung hub assembly — with spring cover relieves for flexibility and heat-treated components for strength — ensures smooth, consistent engagement under demanding conditions.

Key Features:

• Multi-friction disc: carbon semi-metallic on one side, Kevlar on the other for superior torque capacity and wear life
• High-clamp pressure plate for increased clamping force over the standard Stage 2
• Double-sprung hub with heat-treated components for strength and durability
• 15–20% higher torque capacity compared to the Stage 2
• Maintains excellent street drivability and smooth engagement quality
• Kit includes pressure plate, disc, release bearing, and alignment tool
• SFI approved

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

The SPEC Stage 2 Plus is part of SPEC's seven-stage single-disc clutch lineup, purpose-built for drivers who need more than a stock-replacement upgrade without sacrificing daily drivability.
