Stabilus Liftgate Lift Support P/N:3B-029499
Raise and hold the tailgate with a smooth, controlled motion using the Stabilus Liftgate Lift Support (MPN 3B-220389), a 25.41-inch gas-charged lift support with dynamic damping. It's a direct-fit replacement for the 2016-2022 Mercedes-Benz GLC300, 2017-2022 GLC43 AMG, 2018 GLC250, 2018-2020 GLC350E, 2018-2021 GLC63 AMG, and 2018-2021 GLC63 AMG S — see the Buyer's Guide tab for the full list and engine details.
Dynamic damping: A longitudinal velocity-manifold groove pressed into the tube wall lets gas flow around the piston for a fluid opening motion with no bouncing or jerking during cycling. The groove narrows toward the end of the stroke for a gentle, controlled stop.
Corrosion resistance: Part coatings are tested to automotive standards for corrosion resistance.
OE-based design: Built based on the OE design for proper fit, form, and function.
Easy install: Installs with no special tools. For best results, replace in pairs.
Signs the original support may need replacing include a liftgate that drifts down, won't stay up, or opens slowly.

This part cross-references / interchanges with the following part numbers:
What does this lift support do?
It's a gas-charged strut that helps raise the liftgate and hold it open, using dynamic damping to control the opening motion for a smooth, gentle stop.
Which vehicles does the 3B-220389 fit?
It fits the 2016-2022 GLC300, 2017-2022 GLC43 AMG, 2018 GLC250, 2018-2020 GLC350E, 2018-2021 GLC63 AMG, and 2018-2021 GLC63 AMG S. Check the Buyer's Guide tab for details.
Should I replace both supports at once?
For best results, replace the supports in pairs so both sides open and hold with even, balanced motion.
What is dynamic damping?
A velocity-manifold groove in the tube wall controls how gas flows around the piston, delivering a fluid opening motion with no bouncing or jerking and a controlled stop.
Do I need special tools to install it?
No. It's designed for easy installation and requires no special tools. Consult your vehicle service information for the correct procedure.
