Spec Clutch SU333H Stage 2+ Performance Clutch Kit

The Spec Clutch SU333H Stage 2+ Clutch Kit is engineered to bridge the gap between the Stage 2 and Stage 3 clutch systems, delivering a compelling combination of daily drivability and elevated torque capacity. Ideal for moderately modified engines that have exceeded the torque limits of a Stage 2 clutch, the Stage 2+ provides a 15–20% higher torque capacity while retaining the smooth, familiar engagement feel of the Stage 2.

At the core of the kit is a multi-friction, full-faced clutch disc featuring a hybrid material construction — carbon semi-metallic friction material on one side and Kevlar on the other. This dual-material design optimizes both grip and wear characteristics across a wide range of driving conditions. The double-sprung hub incorporates spring cover relieves for added flexibility under load, while heat-treated internal components ensure long-term strength and durability. The included high-clamp pressure plate promotes quick, decisive engagement for efficient power transfer.

• Hybrid friction disc — Carbon semi-metallic on one side, Kevlar on the other, in a full-faced configuration
