Spec Clutch SF013 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch SF013 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand aggressive torque capacity without sacrificing daily drivability. Designed for drivers who need a clutch that can handle serious power while still offering a comfortable, streetable feel, the Stage 3 strikes the ideal balance between performance and practicality.

At the core of this kit is a carbon semi-metallic 6-puck sprung hub disc — the leading puck-style clutch in the industry for drivability, service life, and torque capacity. The sprung hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated internal components deliver strength and long-term durability under both street and race conditions. A high-clamp pressure plate completes the assembly, providing the firm clamping force necessary for high-torque applications.

Kit Includes:

• High-clamp pressure plate
• Carbon semi-metallic 4 or 6-puck sprung hub disc assembly (6-puck standard on most applications; 4-puck available upon request)
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

All Spec clutch kits are designed, hand-built, and tested in the U.S.A. The Stage 3 is part of Spec's street/strip lineup (Stages 1–3+), making it ideal for performance builds that see both road miles and track days.
