Get your clutch engaging smoothly again with the Dorman - First Stop Clutch Slave Cylinder (CS650109). This hydraulic slave cylinder actuates the clutch release mechanism — when you press the pedal, it converts hydraulic pressure sent by the clutch master cylinder into the movement that disengages the clutch. It installs as a direct-fit replacement across a range of Ford Mustang models, so if a leaking or worn slave cylinder is behind a soft pedal or hard shifting, this drops in to replace it.

  • Direct replacement: built to match the original clutch slave cylinder in the listed vehicles.
  • Precise design: reverse-engineered from original equipment to fit and function reliably.
  • Durable materials: aluminum body with high-grade rubber components for compatibility with standard brake fluid.
  • Quality-backed: supported by a team of engineers and quality control experts in the United States.
