Installation Notes and Tips

Verify bore diameter, mounting hole count, and vehicle chassis/VIN breakpoints before installation. Because this unit is not pre-filled, the clutch hydraulic system must be filled and bled after installation. Confirm the push rod and mounting points match the original part before final assembly. For Audi A4, Audi S4, and related applications, check the VIN notes carefully to ensure correct coverage.
