Front Air Suspension Shock Struts w/ADS For Mercedes W166 X166 GL450 GLS550

Front Air Suspension Shock Struts with ADS for Mercedes

These front air suspension shock struts with ADS are a paired replacement set for Mercedes W166 and X166 chassis models including the GL450 and GLS550, restoring adaptive damping and air spring control.

Overview

These front air suspension shock struts with ADS are built to replace worn factory units on Mercedes W166 and X166 SUVs, bringing back adaptive damping and proper ride height. The pair covers both front corners, so the vehicle stays level and responds correctly to changing road conditions. They suit owners of GL450 and GLS550 models who want a matched set rather than mixing old and new struts.

Specs At A Glance

Good To Know

Q: Do both struts need replacing at the same time? A: Replacing the front pair together keeps damping and ride height balanced side to side. Mixing a new strut with an old one can cause uneven handling.

Q: Will the ADS function work after installation? A: The adaptive damping should operate once the struts are installed and any required calibration is completed. A scan tool reset may be needed so the system recognizes the new components.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
