Raybestos SC37680 Clutch Slave Cylinder

Raybestos SC37680 Clutch Slave Cylinder is a direct replacement hydraulic slave for the clutch actuation system in 1986–1994 Nissan D21 Hardbody pickups with a manual transmission. As the slave cylinder, it sits at the end of the hydraulic line and, when the clutch pedal is pressed, pushes a piston to actuate the release bearing and disengage the clutch, enabling smooth gear changes without a mechanical linkage. The SC37680 is designed to match the original equipment mounting pattern and hydraulic port configuration for this application, ensuring proper alignment with the release fork and throwout bearing. In catalogs and cross-references, this part is listed under interchange numbers such as 072-8442, 072-8887, 12425, 13119, and 3062010G00, among others, reflecting its use as a compatible replacement across aftermarket suppliers. Raybestos positions this component within its clutch service parts lineup for the Nissan D21 range, offering a factory-equivalent option for restoring clutch operation on affected vehicles and simplifying maintenance of hydraulic clutch systems.
