2017-2021 Honda Civic EX/Si Clutch Master Cylinder Upgrade Kit by Clutch Masters

When upgrading your clutch, don't overlook upgrading your clutch master cylinder as well. Typically the OEM master cylinder will work just fine, but sometimes that master cylinder is getting old and tired and possibly might be leaking. Or maybe your want just a little bit more crisper pedal feel when operating your clutch. Upgrading to the Clutch Masters Clutch Master Cylinder will make sure your clutch hydraulic system is up to snuff and able to handle more aggressive driving.

This is a complete plug and play kit and includes everything you need to install this system. Will work with OEM slave cylinders.

Alternatively, you can save some money and upgrade your entire hydraulic system by adding on one of our internal hydraulic release bearings that will eliminate your stock slave cylinder and give you a complete performance hydraulic clutch system.

Good to a point

Im giving this 4 stars for one reason. The pedal feel was great. I drove for about a solid 2 months, maybe, and it blew out. I couldnt wait for the whole inspection process to see if i was eligible for a warranty so i bought another one. Again, the pedal feel was great. But this time i barely made it 3 weeks. I guess all i can say is if you plan to continue to use a stock clutch for a low power daily but want a more consistent feel, go for it. But if you swap to anything like ACT, SPEC, or any other HD clutch kit, do your research deeply before buying anything.

Great product, clutch feels way better

Not what I expected

I had this installed on my FK8 at a dealer (I bought this early 2025 and made it tall about august). I drove the vehicle for about 10k and then the pedal would not return after being depressed to the floor. I got stuck and had to have the vehicle towed back to the dealer to have the OEM one reinstalled on the vehicle. I have not called or anything. Paying for an upgraded part only for it not to work not so good. I would just never buy this part again.

Perfect fit and sold

This thing beat my expectations. Talk about solid build quality. Fits perfect. Clutch feel is so much better. Sold. A1 sauce here. I do hope they can build or offer a slave that can take place of the factory w the valve delete until you have time to do a clutch plate replacement and upgrade to the Hydraulic style slave.
