Spec Clutch SF385 Stage 5 Full-Metallic Race Clutch Kit

The Spec Clutch SF385 Stage 5 Clutch Kit is a purpose-built, full-race clutch system engineered for extremely modified drag race and pulling applications. Rated to handle up to 519 ft-lbs of torque, this kit delivers maximum clamping force and friction capability for builds that demand the absolute limit from their drivetrain.

Key Features:

• Full-metallic sintered iron disc with the highest possible friction coefficient for maximum torque transfer
• High-clamp pressure plate for aggressive, positive engagement under extreme power
• Solid 12-rivet rigid hub assembly — heat-treated for strength and durability under race conditions
• SFI approved — clutch kits and flywheels meet SFI safety standards
• Bearing and tool kit included

Intended Use: Drag racing and pulling competitions. The Stage 5's full-metallic disc and rigid hub result in harsh, aggressive engagement characteristics. This clutch is not recommended for street use. Best suited for dedicated race vehicles operating under sustained high-load, high-torque conditions.

The Spec Stage 5 represents the top of the SPEC performance clutch lineup, offering uncompromising grip and heat resistance where a street-friendly setup simply isn't adequate. If you are unsure whether the Stage 5 is right for your build, consult a SPEC technical representative before ordering.
