ACT Mod-Twin 225 HD Rigid Street Clutch Kit 2004-2021 STI

Description:
This is ACT's new Mod Twin 225 HD Rigid Street Clutch Kit. This particular clutch kit blends an easy pedal feel with a smooth but positive engagement with quick-shifting for high-horsepower AWD vehicles. This clutch combines twice the organic friction surfaces with a no-nonsense rigid Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat-treating process that provides a consistent light-pedal feel. Other features include steel-backed friction plates with high-quality organic friction materials that deliver a stable coefficient, good heat capacity, and longer clutch life. The friction plates uniformly transfer torque to a Mono-Drive chrome-moly hub assembly which extends input shaft life and reduces driveline shock from torsional vibration. Ultimately, this package delivers a lightweight and rigid design will provide quicker shits with trouble-free service.
