SiriMoto N1 Clutch Master Cylinder CMC Damper Delete / Bypass Kit for 2025 Honda Civic

Most late-model Honda and Acura vehicles have what is called a Clutch Damper (or Clutch Dampening Diaphragm), which is there to subdue tiny vibrations that permeate through the clutch pedal. These vibrations mainly stem from the release bearing (throw-out bearing) when it engages the pressure plate, but are very minimal and often not an issue by driving enthusiasts' standards.

This factory clutch damper becomes a problem though, as it is prone to leaking or even blowing out completely. In addition, it takes away from the clutch pedal feel since it features a chamber that will increase in volume with raising fluid pressures. This becomes especially apparent with upgraded/aftermarket clutch kits and pressure plates.

At best, the OEM clutch damper will subdue your pedal input, and make quick-shifts difficult if not impossible. And at worst, it can leave you stranded if the master cylinder is no longer able to displace the necessary hydraulic fluid to properly disengage the clutch pressure plate!

The SiriMoto N1 Clutch Damper Delete / Bypass Kit eliminates the dampening diaphragm in the clutch hydraulic circuit by providing a simple replacement assembly that fits in place of the factory damper. This damper delete (or damper bypass) gives the driver better clutch feel, faster shifting, and eliminates a crucial point of failure. For those with upgraded clutches, this damper delete also represents a more robust system that is made to handle high-performance clutch kits and their upgraded pressure plates.

In addition, the kit includes a SpeedBleeder valve to help make installation a breeze! This bleeder valve replaces the factory bleeder screw on the slave cylinder, and allows you to simply crack the valve open, pump the clutch pedal, and relieve any air pockets that would otherwise be trapped in the system.

In essence, this kit includes all of the necessary parts to take any guess-work out of building your own damper delete, saves hours of research, avoids having to buy parts from multiple sources, and should allow you to complete the deletion of the OEM damper quickly!
