Product Details

The Arnott AS-3161 is engineered as a direct replacement air suspension strut for the front left side of the Mercedes-Benz S-Class and Maybach W222 platform. It combines a new air spring sleeve with a monotube shock absorber to restore ride height control, steering stability, and suspension response on vehicles equipped with AIRMATIC and 4MATIC. Arnott’s NEW product line focuses on fully assembled replacement suspension components built from new parts rather than remanufactured cores, and this strut follows that approach with a stamped steel top, CNC-machined base, and durable sealing components.

This part cross-references Mercedes-Benz 2223202100 and 2223202500 for the same application. AS-3161 is a fitment-based replacement for the front left corner on the Mercedes-Benz S560, S550, S500, S450, Maybach S560, and Maybach S550 applications listed below.

What It Helps Fix

• Front-end sagging or uneven ride height
• Air spring leakage at the strut assembly
• Excessive bouncing, harshness, or reduced damping control
• Warning lights related to air suspension performance
• Ride quality changes caused by a worn OE front left strut

Installation Notes

Install AS-3161 on the front left side only. Confirm the vehicle is equipped with AIRMATIC and 4MATIC, and verify that it does not use Active Suspension (ABC) or AMG-specific suspension hardware before ordering. This assembly includes a new airline fitting and mounting hardware, and it is built for direct replacement of the original front left air strut on the listed Mercedes-Benz S-Class and Maybach models.
