Hybrid Racing K Swap Clutch Master Cylinder Upgrade

SKU HYB-CMC-01-02 targets the clutch hydraulics in the 2006–2015 Honda Civic. Factory clutch master cylinders in these applications are known to be unreliable, and design limitations can lead to premature failures that affect drivetrain operation.

High RPM shifting issues are commonly linked to the OE master cylinder's limited fluid transfer to the slave cylinder, which can prevent full disengagement of the clutch and cause grinding or rough engagement during high-RPM shifts. This is a frequent service concern for your customers operating older Civics with higher mileage or frequent high-RPM shifting.

Upgrading the clutch master cylinder and clutch line to our EM1 kit reconfigures the system to a more direct hydraulic path. This change provides a more consistent and direct clutch pedal feel and improves shifting response under high-RPM operation for your installs.

Installation guidance: Review the provided instructions to understand the steps required to address gear-change issues. For your installs, consider upgrading your shifter cables or cable bushings to achieve even crisper gear changes where applicable.

Note: This kit does not repair a broken or damaged transmission.
