When a worn or leaking clutch master cylinder leaves the pedal feeling soft or makes shifting difficult, the Dorman - First Stop Clutch Master Cylinder CM39598 supplies the hydraulic pressure that disengages your clutch. It drops in as a direct-fit replacement for the 1984-1987 Nissan 200SX (L4-1.8L), 1984-1988 Nissan 200SX (L4-2.0L), and 1987-1988 Nissan 200SX (V6-3.0L).

The clutch master cylinder converts clutch-pedal movement into hydraulic pressure, pushing fluid to the slave cylinder so the clutch can release. If a failed master cylinder is the cause of a soft pedal or hard shifting, this unit is designed to replace it.

  • Direct replacement: reverse-engineered from the original equipment to install and operate like the factory clutch master on the listed vehicles.
  • Durable materials: high-grade rubber components compatible with standard brake fluid.
  • 0.625 in. bore: 5/8 in. inside diameter; Standard Replacement grade.
  • Quality-backed value: supported by a team of engineers and quality-control experts in the United States.
