Bring back a smooth, controlled ride on the front right corner with the Arnott Industries Air Suspension Strut AS-3408, a complete assembly built with OE-quality components for the right-hand side of the Mercedes-Benz GL/GLS and ML/GLE equipped with Airmatic and ADS. It drops in as a direct-fit replacement for the listed applications, pairing a model-specific shock absorber with an air spring in one Arnott-engineered unit designed to improve ride comfort and handling.

  • Continental ContiTech air spring sleeve: a premium multi-layer, cross-corded sleeve protected by an aluminum can and dust cover for added strength and extended service life.
  • Tier 1 hardware: formed steel top mount, O-rings, polyurethane bump stop, airline fitting and check valve.
  • Heavy-duty crimping rings secure the sleeve for a reliable seal.
  • Converts active to passive at this corner. Model-specific shock absorber tuned to the application.

For best results, it is recommended to replace in pairs.

Frequently Asked Questions

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.
