ACT HC12-HDSS Heavy Duty Clutch Kit

If you're a proud owner of a 2024 Acura Integra or a Honda Civic (2016-2020), including the Civic Type-R (2017-2021 & 2023-2024), the ACT HC12-HDSS Heavy Duty Clutch Kit is an upgrade you won't want to miss. This kit features ACT's top-selling Heavy Duty pressure plate paired with a robust street disc, designed specifically for enthusiasts who demand performance without sacrificing daily drivability.

Performance-Driven Design

The ACT Heavy Duty pressure plate utilizes an exclusive diaphragm design that boosts clamp load, minimizes deflection, and extends clutch life. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring it can handle the heat and stress of spirited driving or track days. The precision cover stampings enhance rigidity and consistency, making this clutch system reliable under high RPMs.

Street-Ready Clutch Discs

ACT?s Performance Street discs are crafted from premium organic materials with a high copper content, optimizing heat transfer and increasing durability. The steel-backed lining significantly improves burst strength, while the reduced marcel allows for quicker shifts, perfect for those who appreciate seamless gear changes. Whether you're carving through mountain roads or hitting the track, this kit delivers the performance you need.
