Losing clutch feel or spotting hydraulic fluid near the bellhousing? The Dorman - First Stop Clutch Slave Cylinder CS123693 is the externally mounted hydraulic unit that converts pressure from the clutch master cylinder into the mechanical push that moves the release fork and disengages the clutch. It installs as a direct-fit replacement across a range of medium-duty cab-forward trucks, including the 1987-1998 Chevrolet W4500 Tiltmaster and Isuzu NPR, the 1995-1998 Chevrolet W3500 Tiltmaster, and GMC W3500 Forward and W4500 Forward models.

  • Direct replacement: reverse-engineered from the original equipment slave cylinder to fit and function like the factory unit on the listed applications.
  • 1-inch bore: built to a 1 in inside diameter to match the original hydraulic geometry.
  • High-grade rubber components: seals designed for compatibility with the standard brake fluid used in the clutch hydraulic system.
  • Quality-checked: backed by a team of engineers and quality-control experts in the United States.

This is an external-type slave cylinder. If a leaking or worn slave cylinder is behind a soft pedal or hard shifting, this replaces it. Country of origin: Taiwan.

What fluid does it use?
