The Action Clutch Stage 3 (1MS) Clutch Kit, part number aonACR-3421, is engineered for the 2022 Honda Civic Si with the 1.5L L15B7 turbocharged engine. Designed for heavy-duty street use and occasional drag, road, or drift racing, this performance clutch kit delivers a 170% increase in holding capacity over the factory clutch while maintaining a strong balance of control, durability, and drivability. The kit includes a lightweight chromoly flywheel and a Sprung MIBA Ceramic disc available in a 4-puck or 6-puck configuration, depending on the selected application.
The heavy-duty single-diaphragm pressure plate and reinforced drive straps are built to withstand demanding conditions and increased drivetrain loads. The sprung ceramic disc provides quicker engagement and improved power transfer, making this kit well suited for low- to mild-horsepower vehicles seeking enhanced performance. Some clutch chatter may occur during initial operation, but it should decrease after the recommended break-in period. The included lightweight chromoly flywheel helps improve engine response while supporting consistent clutch operation.
Action Clutch incorporates patented, fully enclosed spring retainers to help prevent springs from dislodging and causing engine or transmission damage. Each kit is quality checked and approved by an experienced Action Clutch engineer before release, providing added confidence in consistent performance and safety. This Stage 3 clutch kit is designed for drivers who want increased holding power and responsive engagement without giving up everyday usability.
Professional installation is recommended, along with following all manufacturer break-in procedures to ensure proper seating and long-term performance. This kit fits the 2022 Honda Civic Si and is intended for compatible 1.5L L15B7 turbo applications. California Proposition 65 warning applies.
