Arnott AS-3365 Air Suspension Strut - Rear Left

Rear Left Air Strut for Mercedes-Benz W222

The Arnott AS-3365 is a new rear left air suspension strut for select 2014-2020 Mercedes-Benz S-Class and Maybach W222 chassis vehicles with Airmatic. It is built as a direct OE-style replacement for the rear left corner and uses a custom tuned Eibach shock absorber for controlled ride quality and consistent handling.

Arnott AS-3365 is assembled in the USA and uses a multi-ply Continental ContiTech air spring sleeve protected by an aluminum can. The design also includes long-lasting seals, O-rings, a bump stop, heavy-duty crimping rings, a new air fitting, connector valve, and a dust boot to help protect the air spring assembly.

Product Details

This Arnott NEW line air suspension strut is engineered for Mercedes-Benz S-Class and Maybach models using Airmatic suspension without ABC, including 4Matic and AMG applications where listed. It is a direct replacement for OE part numbers and is designed for the rear left position on the W222 chassis. The AS-3365 is a practical choice for restoring ride height control, damping response, and air spring function on a Mercedes-Benz S450, S560, S63 AMG, or Maybach S650 with the correct suspension setup.

This part cross-references Mercedes-Benz OE numbers such as 2223202900 and 2223207313 for the same application.

Common Issues This Part Can Address

• Rear suspension sag or loss of ride height
• Air spring leakage at the strut assembly
• Uneven rear stance on the left side
• Excessive bouncing or reduced damping control
• Warning lights related to air suspension performance

Before installation, confirm the vehicle uses Airmatic suspension without ABC and verify the rear left mounting configuration on the W222 chassis. The AS-3365 is built with a loop/eyelet lower mount and stud upper mount, so matching the original layout is important for proper installation.

Quality Assurance

Arnott’s NEW line focuses on new, application-specific suspension components rather than remanufactured assemblies. The AS-3365 is assembled in the USA with branded air spring materials and new sealing components for consistent fit and function.
