Spec Clutch SI473H Stage 2 Plus Clutch Kit

The SPEC SI473H Stage 2 Plus Clutch Kit is engineered for modified engines that exceed the torque capacity of the standard Stage 2 clutch. It retains the familiar, street-friendly engagement feel of the Stage 2 while delivering a significantly higher torque capacity — making it an ideal upgrade for performance builds that still require daily drivability.

At the heart of this kit is a high-clamp pressure plate paired with a composite multi-friction carbon-Kevlar disc, offering aggressive torque handling with excellent wear resistance. The high-torque sprung hub and disc assembly absorbs drivetrain shock for smoother engagement and extended component life.

Key Features:

• High-clamp pressure plate for increased torque capacity
• Composite multi-friction carbon-Kevlar friction material
• High-torque sprung hub and disc assembly for smooth engagement
• Excellent wear characteristics for extended service life
• Retains Stage 2 pedal feel for comfortable street driving
• Includes bearing and installation tool kit

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

The SPEC Stage 2 Plus is the performance-focused step up from the Stage 2, purpose-built for drivers who demand more torque capacity without sacrificing day-to-day usability.
