Installation Notes
Fits 2003-2007 Infiniti G35 and 2003-2006 Nissan 350Z. Verify hydraulic line routing, pedal connection, and system condition before installation. Because this unit is not pre-filled and not pre-bled, the clutch hydraulic system will need to be filled and bled after installation. The included installation instructions and push rod support the replacement process, but the clutch slave cylinder is not included.
Quality Assurance
LuK is recognized for its long-standing development work in hydraulic clutch release systems through Schaeffler engineering. This new replacement part is built for direct service use in manual transmission clutch hydraulic repairs.
