Spec Clutch SZ372 Stage 2 Kevlar Clutch Kit

The Spec Clutch SZ372 is a Stage 2 performance clutch kit engineered for mild to moderately modified naturally aspirated and power-adder engines. It delivers an ideal balance of street drivability and enhanced performance, making it equally well-suited for stock power builds focused on longevity and spirited daily driving.

Key Features:

• Pure Kevlar friction disc — segmented or full-faced with steel backing for excellent wear resistance and long service life
• High-clamp pressure plate — increases clamping force over stock for improved torque capacity
• High-torque sprung hub and disc assembly — double-sprung design with spring cover reliefs for flexibility; heat-treated components for strength and durability
• Release bearing and alignment tool included — everything needed for a complete installation
• Stock-like pedal feel — smooth, predictable engagement suitable for everyday street use

Intended Use: Street, Drag, Pulling, Autocross

The SPEC Stage 2 kit steps up torque capacity and wear life compared to the Stage 1, while maintaining the streetable engagement quality drivers expect. It is the preferred choice for enthusiasts who want a direct upgrade over the factory clutch without sacrificing daily drivability.
