Detailed Description

Arnott AS-3897 is a new air suspension strut engineered for the front left-hand side of the Mercedes-Benz W212 chassis. It is designed for vehicles equipped with Airmatic and ADS, and it is not for 4Matic models. The assembly pairs a model-specific shock absorber with an integrated air spring to maintain proper ride height and deliver consistent damping performance. This part number, AS-3897, is a direct-fit replacement for select Mercedes-Benz E200, E250, E300, E350, E400, E500, E550, and E63 AMG applications.

The Arnott New product line focuses on new, application-specific suspension components rather than remanufactured units. AS-3897 uses a premium Continental ContiTech air sleeve, protected by a dust cover, along with a machined aluminum top mount and new airline fitting. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Front-left corner sagging or loss of ride height
• Air spring leakage causing suspension warning lights
• Excessive bounce, harshness, or reduced damping control
• Uneven stance on Mercedes-Benz E Class air suspension systems
• Noisy or worn suspension response from an aging strut assembly

Installation Notes and Tips

Verify that the vehicle is a 2010-2016 Mercedes-Benz E Class with Airmatic and ADS and without 4Matic before ordering. Confirm the front left position and match the original mounting style, including the center eye body end, bracket lower mount, and stud upper mount. Inspect the airline connection and surrounding suspension components during replacement to help ensure a proper seal and correct operation.
