Product Details

Arnott REMAN AS-3359 is engineered for the front left corner of Mercedes-Benz vehicles equipped with Airmatic suspension and without 4MATIC. The OE strut is inspected, steam cleaned, media blasted to bare metal, then rebuilt with fresh shock oil and replacement internal components before being dyno and functionally tested. This remanufactured air suspension strut is assembled in the USA and cross-references Mercedes-Benz part numbers 2223204713 and 222320471389. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with Mercedes-Benz S450, S450L, S560, S560e, S560L, S400L, S550, S550e, S500, S500L, S600, S600L, S65 AMG, S65L AMG, and S400 front left applications listed in the fitment data. Search terms such as Mercedes-Benz S-Class front left air strut replacement, W222 Airmatic remanufactured strut, and Arnott AS-3359 front left suspension strut all point to this application.

What It Helps Address

• Front-end sag from a worn air spring or leaking bladder
• Excessive bouncing or poor damping from a tired shock assembly
• Uneven ride height at the front left corner
• Air leaks at the strut, sleeve, or airline connection
• Noisy or unstable ride caused by worn internal strut components

Installation Notes

Verify Airmatic suspension and confirm the vehicle is not equipped with ABC before ordering. This strut is for the front left side only and is not for 4MATIC applications. Inspect the airline, mounting points, and related suspension components during installation to help prevent repeat failures. Follow Mercedes-Benz service procedures for air suspension depressurization and calibration after replacement.

Quality Assurance

Each Arnott AS-3359 remanufactured strut is rebuilt from an OE Mercedes-Benz core, then tested for damper performance and function before release. The assembly uses corrosion-resistant coating and Continental ContiTech air sleeve components, and it is backed by Arnott’s industry-leading warranty.
