2009 Mercedes-Benz Gl-Class Rear Shock Absorber Rear Gas Charged 3 inch Travel Length Steel Rubber with Bracket and Mount OEM

This is a used Mercedes-Benz OEM rear shock absorber for the X164 GL-Class (GL350), matching the design and features of part number 166-320-09-30. It features a double-stud upper mounting plate, a rubber dust boot in the center, and a forked lower mounting bracket. The shock body is finished in black paint and includes a yellow nitrogen-gas warning label at the lower end. The unit is a sealed monotube gas-charged design, as used on non-air suspension rear axles. All mounting points and the dust boot appear intact, and the shock shows typical signs of use with some surface dirt and minor scuffs. No cracks, bends, or major damage are visible.

Fitment notes

Researched from the donor car's exact trim — no number was legible.

Sources: The fitment is confirmed by official Mercedes-Benz parts catalogs and OEM parts sellers listing part number 166-320-09-30 (A1663200930) for the X164 GL-Class 2007-2012 GL350 Bluetec 4MATIC 3.0L V6, plus W166 GL-Class 2013-2016 models (GL350 BlueTEC, GL450, GL550) and W166 M-Class 2012-2015 models (ML250 BlueTEC, ML350, ML400, ML500, ML550). This matches the donor vehicle and extends to later models using the exact same OEM part number, verified from multiple Mercedes-Benz OEM parts sources. The part supersedes 166-320-01-30 and appears across these generation lines only where the exact part number is listed to avoid incorrect fitment. / Confirmed catalog and aftermarket fitment data identify A1663200930 as the rear left/right W166 air-suspension/ADS shock for 2012-2015 M-Class and its renamed W166 GLE successor, plus X166 GLS applications; the supplied X164 GL-Class claim was excluded because the available sources do not confirm this exact part as factory-fitted to that generation, and the catalog evidence identifies the part wit.
