Spec Clutch SP123H Stage 2 Plus Clutch Kit

The Spec Clutch SP123H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver. Bridging the gap between the Stage 2 and Stage 3 clutch lines, the Stage 2 Plus delivers the familiar street-friendly engagement feel and drivability of the Stage 2 while offering a 15–20% higher torque capacity — making it an ideal upgrade for high-performance builds without sacrificing daily usability.

The disc features a full-faced, multi-friction configuration with carbon semi-metallic material on one side and Kevlar on the other, providing strong torque transfer alongside excellent wear characteristics. The double-sprung hub incorporates spring cover reliefs for flexibility, while heat-treated internal components ensure long-term strength and durability under demanding conditions.

Kit Includes:

• High-clamp performance pressure plate
• Multi-friction composite disc — carbon semi-metallic / Kevlar full-faced configuration
• High-torque double-sprung hub and disc assembly

The SP123H is a direct-fit performance upgrade designed for drivers who need more holding capacity than a Stage 2 can provide but want to retain smooth, streetable clutch engagement.
