2009 Mercedes-Benz Gl-Class Rear Air Suspension Air Spring Rear Left Strut with Bracket and Mounting Hardware 166 320 03 25

This is a used Continental ContiTech air suspension strut, OEM version for the Mercedes-Benz GL-Class (X164) rear left or right, as supplied for model years 2007–2012. The part features the Continental/ContiTech logo molded into the rubber air spring, a green paint mark on the top metal plate, and a pressure-warning label dated 11.08.16. The top plate includes two threaded studs and a central hex nut, and the lower end has the characteristic forked mounting bracket for rear suspension fitment. The black rubber bellows are intact, and the original supplier label (A-2575) with serial number is present. The strut shows typical signs of use, including surface dirt and minor wear, but all mounting points and labels are intact.

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

Sources: Based on OEM part catalog listings (mbparts.mbusa.com) and retailer fitment tables (Amazon, AutoDoc) that explicitly list the part 166‑320‑03‑25 as compatible with X164 GL‑Class (2007‑2012), W166 GLE‑Class (2015‑2018) and X166 GLS‑Class (2015‑2019). / Confirmed for the X164-generation GL-Class: 2007–2009 GL320, 2010–2012 GL350, 2007–2012 GL450, and 2008–2012 GL550; later GL/GLS and ML/GLE listings describe other generations or aftermarket cross-reference claims rather than factory fitment for this exact X164 application.[3][4][10].
