Spec Clutch SB273F Stage 3 Plus Performance Clutch Kit

The SPEC SB273F Stage 3 Plus Clutch Kit is the flagship performance clutch stage engineered for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can handle. Designed for high-powered builds requiring a manageable, friendly engagement feel, the Stage 3 Plus delivers outstanding drivability without sacrificing performance.

At the heart of this kit is a full-faced carbon metallic friction disc that provides an exceptional combination of longevity, friction coefficient, and daily driveability in a single package — a step up from the 6-puck design of the Stage 3. The hub features a double-sprung design with spring cover reliefs for increased flexibility, along with heat-treated components for long-term strength and durability under extreme loads.

Kit Includes:

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

Ideal Driving Applications:

• Street / Daily Driving
• Drag Racing
• Drifting
• Road Racing
• Pulling
• Autocross
• Rally

The SPEC Stage 3 Plus offers superior wear characteristics and better overall manageability compared to the Stage 3, making it the ideal choice for serious performance builds that still see regular street use.
