Detailed Description

Arnott AS-2792 is a front air suspension strut designed for Mercedes-Benz vehicles that use Airmatic and ADS. It replaces the original equipment strut with a new assembly that combines an air spring, hydraulic damper, and mounting components in one unit. The shock absorber is custom valved to help restore original ride control and performance on the road.

This part cross-references Mercedes-Benz OE numbers 1643204313 and 1643204413 for the same application. AS-2792 is a direct-fit solution for front suspension service on the Mercedes-Benz ML-Class and GL-Class, including 2006-2011 ML350, 2006-2011 ML500, 2008-2011 ML550, 2007-2009 ML320, 2010-2012 GL350, 2007-2012 GL450, 2008-2012 GL500, and 2008-2012 GL550 models with the listed suspension systems.

Common Problems This Part Addresses

• Front-end sagging from a worn air spring bladder
• Excessive bouncing or reduced damping control
• Suspension warning lights related to air strut wear
• Uneven ride height at the front of the vehicle
• Noisy or harsh ride from a failing strut assembly

Installation Notes and Tips

AS-2792 is pre-assembled to simplify replacement, but installation should be performed with the vehicle properly supported and the air suspension system depressurized before removal. Verify ADS and Airmatic compatibility before ordering, since fitment varies by model and suspension configuration. After installation, clear any stored fault codes and perform a ride-height check.
