Spec Clutch SS183H Stage 2 Plus Clutch Kit with Carbon-Kevlar Disc

The SPEC SS183H Stage 2 Plus Clutch Kit is engineered for modified, high-output engines that have outgrown the torque capacity of a standard Stage 2 setup. Bridging the gap between the Stage 2 and Stage 3, this kit delivers 15–20% higher torque capacity while preserving the smooth, street-friendly engagement feel that Stage 2 is known for.

At the heart of the kit is a multi-friction composite disc in a full-faced configuration, combining carbon semi-metallic material on one side with Kevlar® on the other. This hybrid construction maximizes grip and heat resistance while maintaining excellent wear characteristics for long service life. The double-sprung hub features spring cover reliefs for added flexibility, and heat-treated internal components provide the strength and durability demanded by aggressive driving environments.

Key Features:

• High-clamp performance pressure plate for increased clamping force
• Composite multi-friction disc — carbon semi-metallic on one side, Kevlar® on the other
• Full-faced disc configuration for consistent, predictable engagement
• Double-sprung hub with spring cover reliefs for smooth, flexible operation
• Heat-treated hub components for enhanced strength and longevity
• 15–20% higher torque capacity versus the standard Stage 2 kit
• Bearing and installation tool kit included
• Designed, hand-built, and tested in the U.S.A.

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

The SPEC Stage 2 Plus is the ideal upgrade for enthusiasts who need more torque-handling capability without sacrificing the daily drivability of a street-oriented clutch.
