Installation Notes and Tips

Verify the vehicle’s liftgate configuration before ordering, since the fitment notes distinguish between power liftgate and non-power liftgate applications. Compare the compressed length, extended length, rod diameter, tube diameter, and socket style to the original support before installation. Confirm that the attachment points use 10 mm end diameters and plastic socket connections. For best results, replace only with the correct application listed for your Mercedes-Benz GLK model year and liftgate setup.
