Spec Clutch SB993H-2 Stage 2 Plus Performance Clutch Kit

The Spec Clutch SB993H-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. Designed for drivers who demand more torque capacity without sacrificing everyday drivability, the Stage 2+ delivers 15–20% higher torque capacity over the standard Stage 2 while maintaining smooth, predictable engagement characteristics.

At the core of this kit is a multi-friction, full-faced clutch disc featuring a hybrid material construction — carbon semi-metallic on one side and Kevlar® on the other. This combination provides excellent heat resistance, aggressive power transfer, and long service life across a wide range of driving conditions. The hub is double-sprung with spring cover reliefs for enhanced flexibility under high-stress conditions, and heat-treated components throughout ensure lasting strength and durability.

A high-clamp pressure plate rounds out the assembly, delivering firm, responsive engagement that puts power to the ground efficiently. All necessary hardware including a bearing and installation tool kit is included for a complete clutch service.
