Spec Clutch SI472 Stage 2 Kevlar Clutch Kit with Alignment Tool

The SPEC SI472 Stage 2 Clutch Kit is engineered for drivers who demand more than a stock clutch can deliver without giving up the everyday drivability they rely on. Ideal for mild to moderately modified naturally aspirated engines as well as power-adder applications, this kit also performs exceptionally well at stock power levels where long service life and smooth engagement are the priority.

Key Features:

• Pure Kevlar friction disc — segmented or full-faced Kevlar disc with steel backing delivers excellent wear characteristics and longer service life compared to Stage 1
• High clamp pressure plate — increased clamping force handles elevated torque demands while maintaining a manageable pedal feel
• High-torque sprung hub and disc assembly — double-sprung hub absorbs driveline shock and reduces wear on transmission components
• Release bearing included — complete kit includes the throwout/release bearing for a straightforward installation
• Alignment tool included — simplifies disc centering during installation

Intended Use: Street, Drag Racing, Autocross, and Pulling

The SPEC Stage 2 strikes the ideal balance between holding power and daily drivability. The pure Kevlar lining provides the smooth, progressive engagement of a stock clutch while offering meaningfully higher torque capacity and wear life — making it a smart upgrade for performance enthusiasts who spend time both on the street and the strip.
