Goodridge Line Upgrade Kit & Clutch Master Cylinder - 06-15 Civic Si / 05-06 RSX

Factory clutch master cylinders in the 06-15 Civics and 02-06 RSX's are known to be rather unreliable and because of their poor design and quality, it can lead to premature failures of critical parts throughout the drivetrain.  High RPM grinds are mostly attributed to the OE master cylinders inability to transfer fluid effectively to the slave cylinder, thus causing grinding and rasping of the gears and synchros since the clutch disk hasn’t fully disengaged.

Upgrading the clutch master cylinder and clutch line to this OEM CMC & Goodridge line kit changes the system to an older, more direct and efficient system. This improvement allows the driver to feel a more consistent and direct clutch pedal which also improves shifting at high rpms.

This kit will not fix a pre-broken or damaged transmission.


  • Helps to eliminate grinds during hard shifts
  • OEM Honda master cylinder
  • Goodridge black coated stainless steel braided clutch line w/fittings
  • Improves the feel of gear changes

Vehicle applications: 06-11 Civic Si (K20Z3), 12-15 Civic Si (K24Z7), 05-06 RSX Base & Type-S (M/T).

Note: Clutch line is designed to mate to a 06-15 Civic K20Z3, 05-06 RSX (K20Z1/K20A3), and K24Z7 style clutch slave cylinder.
