Spec Clutch SF003F Stage 3 Plus Clutch Kit

The SPEC SF003F Stage 3 Plus Clutch Kit is SPEC's flagship performance clutch designed for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can deliver. Engineered for drivers who need maximum holding power without sacrificing daily drivability, the Stage 3 Plus strikes the ideal balance between aggressive performance and manageable street manners.

At the heart of this kit is a full-faced carbon semi-metallic friction disc — a key advantage over the puck-style Stage 3 disc. This full-faced design delivers superior drivability characteristics, extended wear life, and an excellent friction coefficient across a wide range of operating conditions.

Kit Includes:

• High-clamp performance pressure plate
• Full-faced carbon semi-metallic friction disc
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Key Features:

• Full-faced carbon semi-metallic disc — unparalleled life, friction coefficient, and drivability in a single package
• Double-sprung hub with spring cover reliefs for drivetrain flexibility and smooth engagement
• Heat-treated hub components for long-term strength and durability under high-load conditions
• High-clamp pressure plate engineered to handle elevated torque demands of modified engines
• Improved wear characteristics and better engagement manageability compared to Stage 3
• Made in the U.S.A.

Intended Use: Street, Drag Racing, Drift, Road Racing, Pulling, Autocross, Rally

The SPEC SF003F Stage 3 Plus is the ideal solution for performance builds that have outgrown a standard Stage 3 clutch but still require confident, predictable engagement for street use. Requires use of a compatible SPEC flywheel.
