Spec Clutch SM485 Stage 5 Performance Clutch Kit

The Spec Clutch SM485 Stage 5 Clutch Kit is a full-race-grade clutch system engineered for heavily modified drag race and pulling applications. Sitting at the top of SPEC's single-disc clutch lineup, the Stage 5 kit is purpose-built for maximum power transfer where aggressive, uncompromising engagement is required.

Key Features:

• Full-metallic friction disc — delivers the highest possible friction coefficient for maximum torque grip
• Solid 12-rivet hub — rigid, unsprung hub assembly rated for extreme torque loads
• Heat-treated disc assembly — enhances strength and long-term durability under race conditions
• High-clamp pressure plate — maximizes clamping force for reliable power transfer
• Torque capacity: 669 ft/lb
• SFI Approved — meets SFI safety certification standards
• Bearing and tool kit included

Ideal Applications: Drag racing, pulling competitions, and other high-load motorsport environments requiring a no-compromise clutch system.

Important Note: The Stage 5 is street-drivable but not street-friendly due to its aggressive, harsh engagement characteristics. This kit is best suited for dedicated race vehicles. Custom configuration is available — consult a SPEC technical representative to ensure proper setup for your specific application.
