If you need a replacement suspension airbag and don't want to spend the money, this bag is for you. I installed it about a month ago and it's still working. It is identical in quality to OEM. Don't make the mistake of paying $600 to $700 for an airbag and installation. (that was my quote from the dealer setup). You can easily install these yourself. Installed on a 2007 Mercedes GL450. UPDATE: OCTOBER 7, 2020 - Airbag still works! No problem. Just wanted to give an update of the installation.
