Dorman - First Stop Clutch Master Cylinder P/N:CM39717
$56.99
Firm, predictable clutch action starts with a healthy hydraulic master cylinder, and the Dorman - First Stop Clutch Master Cylinder CM39717 takes over that job on the 1984-1988 Chevrolet Corvette (V8-5.7L). It converts your pedal effort into the hydraulic pressure that operates the clutch, and it drops in as a direct replacement reverse-engineered from the original equipment to fit and function like the factory unit.
- Direct replacement: built to match the original clutch master cylinder on the listed vehicles for a straightforward swap.
- Precise design: reverse-engineered from original equipment to fit seamlessly and operate reliably.
- Durable materials: includes high-grade rubber components compatible with standard brake fluid.
- Key specs: 0.688 in bore, M12 x 1.0 outlet thread, and M12 port thread.
Inside the cylinder, a piston and seals pressurize the fluid routed to the clutch slave cylinder, disengaging the clutch when you press the pedal. Signs this part may need replacing include external fluid leaks, a soft or sinking clutch pedal, or trouble shifting. If a failed master cylinder is the cause of those symptoms, this unit replaces it; diagnose the hydraulic system first, since the slave cylinder or lines can produce similar issues. Backed by a team of engineers and quality-control experts in the United States. Country of origin: Taiwan.
