Spec Clutch SZ263H Stage 2 Plus Performance Clutch Kit

The SPEC SZ263H Stage 2 Plus Clutch Kit is purpose-built 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, this kit delivers 15–20% higher torque capacity while preserving the smooth engagement feel and excellent daily drivability of the Stage 2.

The disc features a full-faced, multi-friction design with carbon semi-metallic material on one side and Kevlar® on the other, offering an ideal balance of grip, wear resistance, and street-friendly engagement. The double-sprung hub includes spring cover reliefs for added flexibility, and all hub components are heat-treated for long-term strength and durability.
