SPEC SU072 Stage 2 Kevlar Clutch Kit Full Face Sprung Hub

The SPEC SU072 Stage 2 Clutch Kit is a high-performance clutch solution engineered for mild to moderately modified naturally aspirated and power-adder engines. It delivers the ideal balance of street drivability and elevated torque capacity, making it equally at home on daily-driven vehicles and performance builds.

At the heart of the Stage 2 kit is a full-face, pure Kevlar® friction disc with steel backing. This lining provides excellent drivability characteristics comparable to the Stage 1, while offering slightly longer service life and higher torque handling capability. The sprung hub assembly is double-sprung with spring cover reliefs for added flexibility, and features heat-treated components for enhanced strength and long-term durability.
