Detailed Description

The Arnott AS-3058 is a premium replacement air suspension strut for the 2007-2012 Mercedes-Benz GL-Class and 2006-2011 Mercedes-Benz ML-Class SUVs that use AIRMATIC and do not have Adaptive Suspension (ADS). It is built around Tier 1 components, including a ContiTech air sleeve and a custom-tuned passive Eibach monotube damper, to maintain factory-style ride quality and handling response. This part number, AS-3058, is a direct-fit front suspension solution for select GL350, GL450, GL500, GL550, GL320, and ML450 applications. This part cross-references Mercedes-Benz OE numbers 1643204513 and 1643206113 for the same application.

What It Helps Fix

• Front-end sag caused by a worn air spring or leaking bladder
• Uneven ride height at the front of the vehicle
• Excessive bouncing or reduced damping control
• Air leaks from aging fittings, seals, or crimp points
• Noisy or unstable front suspension performance
