The clutch slave cylinder is a component found on vehicles equipped with manual transmissions. It works together with the clutch master cylinder to disengage the clutch when the pedal is pressed so that the transmission can be safely shifted. The clutch slave cylinder receives pressure from the master cylinder and extends a rod, which will push against a fork or lever to disengage the clutch. To ensure that you get the correct clutch slave cylinder, it is best to check the size and shape of the one currently installed so you can compare with the listed parts. Some important information for selecting the correct clutch component is the type of cylinder needed; fitment position (for left or right hand driven vehicles), piston diameter and date limitation of the unit. As car manufacturers regularly update certain peripherals and design of their models, some clutch slave cylinders will only be suitable for particular models of certain years.
