K-Tuned K-Series Slave Cylinder
The K-Tuned Slave Cylinder is a great upgrade for those wanting to increase their clutch system performance and reduce grinding gears. Also perfect to replace leaking or worn out OEM units (generally 60-80k its a good idea to get a new one anyhow). Many new K-Series cars (05-06 RSX, 06+ Civic Si) use a slave cylinder that has an internal oil restrictor that further slows the movement of the fluid. Similar to the master cylinders that have a feedback plate that reduces speed of the movement. This can be problematic as reduce speed can cause the clutch to not fully disengage and engage as quickly as you are shifting. This can lead to prematurely worn synchros or gears due to grinding.
Note: You may need to upgrade your clutch line. Please note the inlet fitting is mounted vertically, certain k-series slave cylinders have an inlet horizontally mounted. Our K-Series Clutch line will work perfectly with this kit, it will have a 90 degree fitting at the slave. It also features a stainless line that gives the pedal a solid feel.

Very happy with the product,no leaking works grate makes shifting smooth. The new HardMotion K series slave cylinder fixed my problem with my old worn out stock OEM Slave, the old slave made shifting stiff and not as smooth was leaking and could of potentialy damaging the transmission with further using a faulty slave cylinder, now with the new HardMotion slave cylinder installed it a night and day difference from how the performances were with the old worn out slave.it's a great investment for your car especially if you have a new freshly built transmission.I'll definitely recommend it if your replacing one out,this is the one you won’t .cant go wrong if your not happy just let them know and you’ll get a full redound no questions asked satisfaction guaranteed.
