Frequently Asked Questions

What does this air suspension strut do?

It's a complete front-left strut assembly combining a custom-valved Eibach shock absorber with a ContiTech air spring to support the corner, control ride motion, and maintain ride height on the listed Mercedes-Benz models.

Which vehicles does the AS-3163 fit?

It's designed for the front-left position on Mercedes-Benz/Maybach models with AIRMATIC & ADS, without 4MATIC, without ABC, and including AMG — see the Buyer's Guide tab for the full application list.

Should I replace both struts at once?

For best results, Arnott recommends replacing air struts in pairs. This listing covers one front-left strut, so order two if you plan to service both sides together.

What does 'converts adaptive to passive' mean?

This assembly is built to replace an adaptive OE air strut and convert that corner to a passive setup while still maintaining the vehicle's air-supported ride height and leveling.

Is this a genuine OE part?

No. It's an Arnott-engineered aftermarket air suspension strut built with OE-quality components as a direct-fit replacement for the worn OE unit, designed and assembled in the USA.
