Use this Stabilus 3B-220389 lift support when replacing a worn Mercedes-Benz GLC hatch strut that no longer holds the liftgate open, opens unevenly, or feels weak during operation. This part cross-references Tuff Support 610834 for the same application.

Common Replacement Reasons

• Liftgate drops after opening
• Hatch feels heavy or difficult to raise
• Power liftgate movement becomes inconsistent
• Original support no longer maintains opening force
• Rear hatch requires replacement due to loss of gas pressure

Installation Notes

Verify the compressed length, extended length, rod diameter, tube diameter, and plastic socket attachment style before installation. Compare the existing support to part number 3B-220389 and confirm the vehicle is equipped with a power liftgate. Replace only with the correct lift support for the listed Mercedes-Benz GLC fitments.
