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

Front Air Suspension Shock Struts for Mercedes

Sold as a pair, these front air suspension shock struts with ADS replace the worn air springs and adaptive dampers on compatible Mercedes W166 and X166 models so the ride height and damping respond correctly again.

Overview

These front air suspension shock struts with ADS are a direct-fit pair for Mercedes W166 and X166 SUVs whose original air struts have lost pressure or damping control. Each strut combines an air spring with an adaptive damping valve, restoring factory-style ride height adjustment and comfort. They suit owners and shops handling a sagging front end or a failed air strut on a Mercedes W166 or X166.

Good To Know

Q: Do I need to replace both front struts at once? A: Replacing the pair together keeps ride height and damping matched side to side and avoids a second teardown soon after. Q: Will these work with the factory ADS system? A: The struts include an adaptive damping valve designed to connect to the original ADS control, so the vehicle can manage damping as intended.

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