Spec Clutch SY383H-2 Stage 2 Plus Performance Clutch Kit

The SPEC SY383H-2 Stage 2 Plus Clutch Kit is a high-performance upgrade engineered to bridge the gap between the Stage 2 and Stage 3 clutch systems. It delivers the smooth street drivability and engagement quality of the Stage 2, while adding 15–20% more torque capacity for drivers who demand more from their drivetrain.

At the core of this kit is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction pairing provides strong, consistent clamping force while maintaining predictable engagement characteristics across a wide range of driving conditions. The hub is double-sprung with spring cover reliefs for added flexibility under load, and all internal components are heat-treated for enhanced strength and long-term durability.
