Dorman - First Stop Clutch Master Cylinder P/N:CM39838
Keep your clutch engaging crisply with the Dorman First Stop Clutch Master Cylinder CM640216. Reverse-engineered from the original equipment, it drops in as a direct replacement for the 2008-2019 Nissan Frontier (V6-4.0L), 2016-2019 Nissan Frontier (L4-2.5L), 2016-2020 Nissan NP300 Frontier (L4-2.5L), and 2008-2015 Nissan Xterra (V6-4.0L). The clutch master cylinder converts pedal force into hydraulic pressure that travels to the slave cylinder to disengage the clutch; if a leaking or worn master cylinder is the cause of a soft, sinking pedal or hard shifting, this unit replaces it.
This cylinder is not pre-bled or pre-filled, so bleed the clutch hydraulic system after installation. Standard Replacement grade, backed by a team of engineers and quality control experts in the United States. Country of origin: Taiwan.
