New, OEM Nissan Slave Cylinder for all Nissan 350Z and Infiniti G35 models equipped with the VQ35DE engine.
Located along the transmission's bell housing, the external slave cylinder found on the earlier 350Z and G35 models can fail after years of usage. Over time, the internal seals can fail causing the clutch pedal to loose pressure. A failure in the slave cylinder can result in a lost ability to engage the clutch, making gear changes nearly impossible.
Z1 Motorsports highly recommends using fresh DOT 3 or higher Brake fluid from companies such as Motul (MOTUL RBF600) when replacing a Slave Cylinder.
