Spec Clutch SF333F Stage 3 Plus Clutch Kit - Full Face Carbon Semi-Metallic

The Spec Clutch SF333F Stage 3 Plus (Stage 3+) Clutch Kit is SPEC's flagship performance clutch, engineered for heavily modified street and race vehicles that demand torque capacity beyond what the standard Stage 3 can handle — while still delivering manageable, daily-drivable engagement. Unlike the Stage 3's puck-style disc, the Stage 3+ uses a full-faced clutch disc for smoother engagement and improved drivability without sacrificing high-performance capability.

The Stage 3+ disc features carbon semi-metallic friction material that delivers an exceptional combination of long service life, high friction coefficient, and street-friendly driveability in a single package. The high-torque sprung hub is double-sprung with spring cover reliefs for added flexibility, and all hub components are heat-treated for maximum strength and long-term durability under extreme loads.

Key Features:

• Full-faced carbon semi-metallic friction disc — superior wear life and drivability vs. puck-style Stage 3
• High-clamp pressure plate for increased torque holding capacity
• Double-sprung high-torque hub with spring cover reliefs for flexibility
• Heat-treated hub components for strength and durability under sustained high loads
• Bearing and tool kit included for complete installation
• Manufactured in the U.S.A. to strict tolerances

Intended Driving Applications: Street, Drag Racing, Drift, Road Racing, Rally, Autocross, Pulling

The SPEC Stage 3+ is the ideal choice for high-powered builds that need a race-worthy clutch without sacrificing the street manners required for daily driving. SPEC clutches are manufactured on-site using advanced production methods and tight tolerances trusted by professional race teams worldwide.
