Spec Clutch SC865 Stage 5 Performance Clutch Kit - Full-Metallic Disc

The SPEC SC865 Stage 5 Clutch Kit is SPEC's highest-performance clutch solution, engineered for extreme motorsport applications including drag racing, tractor pulling, and autocross. Built around a full-metallic friction disc delivering the highest possible friction coefficient, this kit is designed to handle the most demanding high-torque, high-horsepower builds.

Key Features:

• Full-metallic friction disc with the highest available friction coefficient for maximum grip and torque transfer
• High-clamp pressure plate with adjustability available on select applications
• Solid 12-rivet hub assembly for superior strength and rigidity under extreme load
• Heat-treated disc assembly for long-term strength and thermal durability
• Rigid iron disc assembly for consistent, aggressive engagement
• Bearing and alignment tool kit included for a complete installation package

Intended Use:

• Drag racing
• Tractor pulling
• Autocross
• Extreme high-torque street builds (note: not street-friendly due to aggressive engagement characteristics)

The Stage 5 represents the top of the SPEC clutch lineup. While technically street-drivable, its harsh, on/off engagement makes it best suited for dedicated race and competition vehicles. For heavily modified drag race or pulling engines — or any application requiring slipper clutch or progressive torque-induced engagement behavior — the SC865 Stage 5 delivers the holding power and reliability that serious motorsport demands.
