This part cross-references / interchanges with the following part numbers:
Which corner does the AS-3408 fit?
It is the front right air suspension strut for the listed Mercedes-Benz GL/GLS and ML/GLE models equipped with Airmatic and ADS.
Is this a complete assembly?
Yes. It combines a model-specific shock absorber and Continental ContiTech air spring with a formed steel top mount, O-rings, polyurethane bump stop, airline fitting and check valve.
Do I need to replace both sides?
It is sold individually, but Arnott recommends replacing struts in pairs for the most balanced, consistent ride.
What does "converts active to passive" mean?
This corner replaces the electronically adjustable original with a passive strut, using a tuned shock absorber and air spring in place of the active damping unit.
What signs suggest my air strut may need replacing?
Common signs include a sagging corner, a harsh or uneven ride, air leaks, or a suspension warning message. Diagnose the cause before replacing, as other components can be involved.
