About Clutch Slave Cylinders

Clutch slave cylinders for cars, utes, 4WDs and trucks, including external slave cylinders and concentric slave cylinders (CSCs), which sit inside the bell housing.

Slave cylinders are specific to the vehicle and gearbox, so check the details on each listing, or select your vehicle at the top of the page. Replacing the clutch? Check whether your clutch kit already includes a CSC before you order one separately. For the other end of the system, see clutch master cylinders.

Clutch Slave Cylinders FAQs

What does a clutch slave cylinder do?

The slave cylinder receives hydraulic pressure from the master cylinder and pushes the clutch fork or release bearing, which disengages the clutch when you press the pedal.

What are the signs of a bad clutch slave cylinder?

Look for fluid leaking at the gearbox end, a soft or sinking pedal, trouble getting into gear, or a clutch that doesn't fully disengage. A dropping clutch fluid level is another common sign.

What's the difference between an external and a concentric slave cylinder?

An external slave cylinder bolts to the outside of the gearbox and pushes a clutch fork. A concentric slave cylinder sits inside the bellhousing and includes the release bearing, so replacing it means removing the gearbox.

Can I replace a clutch slave cylinder myself?

An external slave cylinder is often a manageable home job: disconnect the line, swap the cylinder and bleed the system. A concentric slave cylinder needs the gearbox removed, so it's best done with the clutch, ideally by a professional.

Should I replace the slave cylinder with a new clutch?

If it's a concentric slave cylinder, yes. It's inside the bellhousing, so replacing it with the clutch avoids pulling the gearbox again. For an external slave, check it and replace it if it's leaking or old.
