Spec Clutch SF745 Stage 5 Clutch Kit - Full-Metallic Drag Race

The SPEC SF745 Stage 5 Clutch Kit is SPEC's most extreme performance clutch, engineered for heavily modified drag race and pulling competition engines, or any application demanding a slipper clutch with progressive torque-induced engagement. This is a race-purpose clutch with aggressive engagement characteristics — it is not intended for street use.

Key Features:

• High-clamp pressure plate — adjustability available on select applications for tuning engagement feel
• Full-metallic rigid iron disc assembly — delivers the highest possible friction coefficient for maximum torque transfer
• Solid 12-rivet hub — heat-treated for exceptional strength and durability under extreme load
• Bearing and tool kit included — everything needed for a complete installation
• Progressive torque engagement — supports slipper clutch setups ideal for drag launches and pulling applications

Because of the highly specialized nature of the Stage 5 platform, SPEC strongly recommends consulting with a SPEC technical representative before ordering to ensure the kit is properly configured for your specific engine output, transmission, and intended use. The unsprung hub design transfers vibration and harshness directly to the drivetrain, making this clutch best suited for dedicated race builds.

Intended Use: Drag Racing, Pulling
