Spec Clutch SY873H Stage 2 Plus Performance Clutch Kit

The SPEC SY873H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver. Bridging the gap between the Stage 2 and Stage 3, the Stage 2 Plus maintains the familiar street-friendly feel and smooth daily drivability of the Stage 2 while delivering a 15–20% higher torque capacity — making it the ideal step up for performance builds that push beyond stock power levels.

At the heart of this kit is a multi-friction composite disc in a full-face configuration, combining carbon semi-metallic material on one side and Kevlar® on the other. This hybrid friction pairing delivers excellent wear characteristics, consistent grip, and broad operating range across street and track environments. The hub features a double-sprung design with spring cover reliefs for added flexibility, along with heat-treated internal components for long-term strength and durability.

Key Features:

• Multi-friction full-face disc — carbon semi-metallic on one side, Kevlar® on the other
• 15–20% higher torque capacity over the standard Stage 2 kit
• High-clamp pressure plate for increased clamping force
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement

• Includes release bearing and installation tool kit

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

The SPEC Stage 2 Plus is the smart upgrade for enthusiasts and racers who need more holding power without sacrificing the drivability and engagement quality they depend on every day.
