Spec Clutch SC273H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SC273H Stage 2 Plus Clutch Kit bridges the gap between the standard Stage 2 and Stage 3, delivering a 15–20% higher torque capacity while preserving the smooth, street-friendly engagement feel of the Stage 2. Engineered specifically for modified engines that have outgrown a standard Stage 2 clutch, this kit is an ideal upgrade for high-performance street cars and motorsport builds alike.

At the core of the Stage 2 Plus is a full-faced, multi-friction composite disc featuring carbon semi-metallic material on one side and Kevlar on the other — a configuration that maximizes both torque handling and wear longevity. The high-clamp pressure plate provides the added clamping force needed to manage increased engine output, while the double-sprung hub with spring cover relieves delivers flexibility and helps absorb driveline shock. All hub components are heat treated for enhanced strength and long-term durability.
