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

ACT Mod-Twin 225 HD Sprung Street Subaru WRX STI

RallySport Direct proudly carries a great selection of quality drivetrain upgrades brought to you by Advanced Clutch Technology.

This is ACT's new Mod Twin 225 HD Sprung Street Clutch Kit. This particular clutch kit is ideal for high-horsepower AWD vehicles and unites uncompromised pedal feel, durability, and engagement quality with high-torque capacity. This clutch combines twice the organic friction surfaces with an ultra-durable spring-center mono-drive hub assembly 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 stable friction coefficient, superior heat capacity, and longer clutch life. The friction plates uniformly transfer torque to a Mono-Drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration.
