Spec Clutch SC152 Stage 2 Performance Clutch Kit - Kevlar Full Face Sprung Hub

The Spec Clutch SC152 Stage 2 Clutch Kit is a high-performance clutch solution engineered for drivers who demand increased torque capacity and extended service life without sacrificing everyday drivability. It is an ideal upgrade for mildly to moderately modified naturally aspirated engines and power-adder applications, while also performing well at stock power levels for spirited street driving.

The Stage 2 kit uses a full-face or segmented pure Kevlar® disc with steel backing, delivering superior wear resistance and a smooth, predictable engagement feel. Compared to the Stage 1, the Stage 2 offers slightly longer service life and a higher torque capacity while maintaining the same excellent street manners. The double-sprung hub features spring cover reliefs for added flexibility, and all hub components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp performance pressure plate for increased clamping force
• Full-face or segmented pure Kevlar® friction disc with steel backing
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement
• Heat-treated hub components for enhanced strength and durability
• Includes release bearing and installation tool kit (where applicable)
• Sold as a complete kit

Intended Use: Street, Drag Racing, Pulling, Autocross

All Spec clutches are designed, hand-built, and tested in the U.S.A. The SC152 is part of Spec's street/strip Stage 1–3+ range, making it a strong choice for performance driving that doesn't require a dedicated race-only setup.

Installation Note: Existing flywheel must be resurfaced prior to installation unless using a new Spec flywheel. A minimum 450-mile break-in period of primarily city/stop-and-go driving is required before full-throttle engagement or speed shifting.
