Spec Clutch SU032 Stage 2 Kevlar Clutch Kit with Sprung Hub

The SPEC SU032 Stage 2 Clutch Kit is engineered for drivers who demand more from their drivetrain without sacrificing everyday usability. Designed for mild to moderately modified naturally aspirated and power-adder engines, this kit also performs exceptionally well at stock power levels where long service life and smooth drivability are the priority.

At the heart of the Stage 2 kit is a full-face pure Kevlar friction disc with a steel backing, delivering improved torque capacity and longer wear life compared to a Stage 1 clutch — while maintaining the smooth, stock-like engagement feel that makes it practical for daily driving. The disc features a double-sprung hub with spring cover reliefs, providing flexibility and cushioning under load. Heat-treated hub components add strength and long-term durability.

Key Features:

• Full-face Kevlar friction disc with steel backing for superior grip and wear resistance

Designed, hand-built, and tested in the USA, the SPEC SU032 Stage 2 Clutch Kit is the ideal step up for performance-minded drivers who want more holding power without compromising daily drivability.
