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

Spectral Performance 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 Rigid Race Clutch Kit. This particular clutch kit is ideal for high-horsepower AWD vehicles that experience aggressive launches and high-performance driving conditions. This clutch combines twice the ceramic 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 puck-style friction plates with high-quality ceramic friction materials that deliver a high friction coefficient, superior 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 drivelinewith one continuous spline. The lightweight rigid design allows for quicker shifts and trouble-free service.
