Spec Clutch SR983H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SR983H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle. Bridging the gap between the Stage 2 and Stage 3, the Stage 2 Plus delivers the same street-friendly drivability and smooth engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — rated up to 267 ft-lbs.

The disc features a full-face, multi-friction composite design with carbon semi-metallic material on one side and Kevlar on the other, offering an ideal balance of holding power, longevity, and daily drivability. The high-clamp pressure plate increases clamping force without sacrificing pedal feel, while the high-torque sprung hub assembly uses double-spring covers with heat-treated components for flexibility, strength, and long-term durability.
