Product Details

Arnott’s New line focuses on replacement air suspension components built for direct-fit service on late-model luxury vehicles. AS-3898 follows that approach with a complete front right air strut assembly for the 2010-2016 Mercedes-Benz E350, 2010-2016 E550, 2012-2016 E300, 2012-2018 CLS550, and other listed E-Class and CLS-Class applications. The design combines an air spring sleeve with a hydraulic internal damper to restore ride height control and road isolation on vehicles equipped with AIRMATIC and ADS. If you are replacing a leaking or worn Mercedes-Benz E-Class front right air strut, AS-3898 provides a new assembly built to OE-style fitment standards. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Front-end sagging or uneven ride height
• Air leaks from a worn air spring sleeve
• Excessive bouncing, harshness, or reduced damping control
• Warning lights related to air suspension performance
• Noisy or unstable ride behavior from a failing strut assembly
