Spec Clutch SD765 Stage 5 Clutch Kit - Full-Metallic Sintered Iron Disc

The SPEC SD765 Stage 5 Clutch Kit is SPEC's highest-performance single-disc clutch solution, engineered for heavily modified drag race and pulling applications that demand maximum torque transfer and aggressive engagement. This race-grade kit features a full-metallic sintered iron disc delivering the highest possible friction coefficient available in a single-disc configuration. While technically street-drivable, this clutch is not street-friendly and is best suited for dedicated competition use.

Key Features:

• Full-metallic friction disc — sintered iron material provides maximum friction coefficient and unmatched torque capacity
• High-clamp pressure plate — delivers extreme clamping force for reliable power transfer under race conditions
• Solid hub disc assembly — 12-rivet solid hub design for high-torque applications with no flex or compliance
• Heat-treated assembly — disc and hub components are heat-treated for superior strength and durability under repeated abuse
• 17-spline input shaft compatibility — 0.938 in. input shaft diameter
• Bearing and tool kit included — everything needed for a complete clutch installation

Intended Use:

• Drag racing
• Pulling competitions
• Extreme street / track duty (not recommended for daily street use)

Important Note: Due to the rigid iron disc assembly and high clamp pressure plate, engagement is harsh and abrupt. This kit is not recommended for street driving and is ideally spec'd in consultation with a SPEC technical advisor based on your specific application and power output. Flywheel not included.
