Spec Clutch SZ232 Stage 2 Performance Clutch Kit

The Spec Clutch SZ232 Stage 2 Clutch Kit is a high-performance upgrade engineered for street-driven vehicles and performance applications. Designed to handle mild to moderately modified naturally aspirated and power-adder engines, the Stage 2 delivers a meaningful step up in torque capacity while maintaining the smooth, stock-like daily drivability that street drivers demand.

At the heart of this kit is a segmented or full-faced pure Kevlar friction disc with steel backing — a proven combination that delivers excellent wear characteristics, longer service life, and higher torque capacity compared to Stage 1 setups. The high-clamp pressure plate increases clamping force to keep up with added power demands, while the double-sprung hub assembly features spring cover relieves for flexibility and heat-treated components for lasting strength and durability.

Key Features:

• Pure Kevlar friction disc with steel backing for excellent life and torque capacity
• High-clamp pressure plate for increased clamping force on modified engines
• Double-sprung hub with heat-treated components (application dependent)
• Stock-like pedal feel and engagement for comfortable daily driving
• SFI-approved components — designed and hand-built in the U.S.A.
• Includes bearing and installation tool kit

Ideal Driving Applications: Street, Drag, Pulling, Autocross

The SPEC Stage 2 is the ideal choice for enthusiasts seeking a noticeable performance improvement over stock without sacrificing the comfort of everyday street use. It is part of SPEC's street-oriented Stage 1–3+ lineup, recommended for street and strip use.
