Spec Clutch SU033 Stage 3 Performance Clutch Kit

The Spec Clutch SU033 Stage 3 Clutch Kit is engineered for heavily modified street and race vehicles that demand high torque capacity without sacrificing daily drivability. Designed to deliver an aggressive yet streetable engagement, this kit strikes the balance between track-ready performance and comfortable pedal feel.

Key Features:

• Carbon semi-metallic friction material — Available in 4 or 6 puck configuration (6 puck is standard on most applications; 4 puck available by request), providing excellent drivability, extended service life, and high torque capacity
• High-clamp pressure plate — Increases clamping force to handle elevated power output from modified engines
• High-torque sprung hub disc assembly — Double-sprung hub with spring cover reliefs for flexibility and heat-treated components for enhanced strength and durability
• Complete kit — Includes pressure plate, disc assembly, release bearing, and installation tool kit
• SFI Approved — Meets SFI safety certification standards

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

The Stage 3 is part of Spec's street/strip clutch lineup (Stages 1–3+) and is recommended for performance builds that require an upgrade beyond stock without moving into a race-only configuration. For best results, the existing flywheel must be resurfaced prior to installation unless a new SPEC flywheel is used.
