Spec Clutch SM383F Stage 3 Plus Performance Clutch Kit

The SPEC SM383F Stage 3 Plus Clutch Kit is the flagship street and race clutch in the SPEC performance lineup, engineered for high-powered applications that demand serious torque capacity without sacrificing drivability. The Stage 3+ steps up from the puck-style Stage 3 with a full-faced carbon semi-metallic friction disc, delivering a more forgiving and consistent engagement feel while still handling aggressive performance demands.

The clutch disc features a full-faced carbon semi-metallic lining that provides an exceptional balance of friction coefficient, long service life, and smooth, predictable engagement characteristics. The hub is double-sprung with spring cover reliefs to absorb drivetrain shock and maintain flexibility under load, while heat-treated internal components ensure long-term strength and durability. A high-clamp pressure plate provides the clamping force needed to transmit power reliably at elevated torque levels.

Key Features:

• Full-faced carbon semi-metallic friction disc for maximum drivability and long service life
• High-clamp performance pressure plate for superior holding power
• Double-sprung hub with spring cover reliefs for flexibility and shock absorption
• Heat-treated hub components for strength and long-term durability
• Includes release bearing and alignment tool kit
• Suitable for street, drag racing, autocross, road racing, rally, drifting, and pulling

As SPEC's top single-disc street stage, the Stage 3+ delivers the ideal combination of high torque capacity and manageable daily drivability. Kit includes all necessary components for a complete clutch replacement.
