Spec Clutch SF233-2 Stage 3 Performance Clutch Kit

The Spec Clutch SF233-2 Stage 3 Clutch Kit is the ultimate street/strip performance clutch solution for high-powered vehicles that demand aggressive engagement without sacrificing daily drivability. Built around a carbon semi-metallic 6-puck sprung hub disc, this kit delivers the ideal balance of high torque capacity, long service life, and comfortable pedal feel — hallmarks of SPEC's industry-leading puck clutch design.

The disc assembly features a double-sprung hub with spring cover reliefs for added flexibility, while heat-treated internal components provide lasting strength and durability under demanding conditions. The high-clamp pressure plate delivers the clamping force needed for performance driving while maintaining a manageable pedal effort. A 4-puck disc configuration is also available for select applications.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic 6-puck sprung hub clutch disc
• High-torque sprung hub and disc assembly
• Release bearing and installation tool kit

Ideal Applications:

• Street performance

Installation Note: Unless using a new SPEC flywheel, the existing flywheel must be resurfaced prior to installation. A minimum 450-mile break-in period — primarily in city or stop-and-go driving — is required before full-throttle engagement or drag launching.
