LuK LSC643 Concentric Clutch Slave Cylinder

The LuK LSC643 is a concentric slave cylinder (CRS) designed for hydraulic clutch release systems. As a critical component in modern manual transmission vehicles, this slave cylinder serves as the final actuator in the hydraulic clutch system, translating hydraulic pressure from the master cylinder into mechanical force to disengage the clutch.

Key Features:

• OEM-quality construction engineered to exact vehicle specifications
• Concentric design integrates the slave cylinder and release bearing into a single unit
• Reduces component count compared to conventional release fork systems
• Located inside the transmission bell housing for direct clutch actuation
• 100% functionally tested to meet OEM performance standards
• Manufactured by Schaeffler, a leading original equipment supplier

LuK, a brand of Schaeffler Group, has been a pioneer in hydraulic clutch actuation technology for decades. The concentric slave cylinder design provides more reliable clutch operation with fewer wear points than traditional external slave cylinder and release fork configurations. This component is precision-engineered to ensure smooth clutch pedal feel and consistent disengagement throughout its service life.
