Spec Clutch SB103H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SB103H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle. Perfectly bridging the gap between the Stage 2 and Stage 3 kits, the Stage 2 Plus delivers the smooth, streetable engagement feel of the Stage 2 while offering a significant performance upgrade for built or boosted applications.

The disc uses a full-faced, multi-friction composite design with carbon semi-metallic material on one side and Kevlar on the other — a proven combination that delivers strong torque handling alongside excellent wear life and daily drivability. Compared to the standard Stage 2, the Stage 2 Plus provides a 15–20% higher torque capacity, making it an ideal choice for enthusiasts who want real performance without sacrificing everyday usability.

Key Features:

• Multi-friction composite disc — full-faced configuration with carbon semi-metallic on one side and Kevlar on the other
