Spec Clutch SF463F Stage 3+ Clutch Kit with Carbon Metallic Disc & High Clamp Pressure Plate

The SPEC SF463F Stage 3+ Clutch Kit is engineered for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can handle. Designed for aggressive performance applications, this kit delivers exceptional holding power while maintaining better daily drivability and manageability compared to the Stage 3—along with improved wear characteristics for extended service life.

At the heart of the Stage 3+ is a high clamp pressure plate paired with a full-faced carbon metallic friction disc, providing aggressive grip and heat resistance under sustained high-load conditions. The high-torque sprung hub and disc assembly helps reduce driveline shock and smooth out engagement, making this kit more street-friendly than a full-race setup despite its impressive torque capacity.

Key Features:

• High clamp load pressure plate for maximum torque holding capacity
• Full-faced carbon metallic friction material for superior heat resistance and durability
• High-torque sprung hub and disc assembly for smoother engagement and reduced driveline shock
• Improved wear characteristics over the standard Stage 3
• Better daily drivability and pedal manageability versus Stage 3
• Includes release bearing and installation tool kit

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

The SPEC Stage 3+ is the ideal upgrade for builds that have surpassed the limits of a standard performance clutch kit and require a high-capacity solution that still tolerates everyday street use.
