Product Details

Arnott AS-3088 is engineered as a direct-fit air suspension strut for the front of 2006-2012 Mercedes-Benz GL-Class and ML-Class SUVs equipped with AIRMATIC, with ADS compatibility on listed GL-Class and ML450 applications. The design combines a hydraulic damper, progressive spring rate, and air-adjustable construction to support consistent front suspension performance. Arnott’s NEW product line focuses on new-build suspension components rather than remanufactured units, and this assembly reflects that approach with a steel upper mount and durable air sleeve construction. This part cross-references Mercedes-Benz OE numbers 1643204313 and 1643204413 for the same application. AS-3088 is a strong match for owners searching for a Mercedes-Benz GL450 front air suspension strut, Mercedes-Benz ML350 front air strut replacement, or a front air suspension strut for GL550 and ML500 models.

Common Problems This Part Can Address

• Front-end sagging from a worn air spring or leaking bladder
• Uneven ride height between left and right front corners
• Excessive bouncing or poor damping response
• Air suspension warning lights related to strut leakage or wear
• Noisy or unstable front suspension operation on AIRMATIC-equipped SUVs

Installation Notes

Verify vehicle equipment before ordering, especially AIRMATIC and ADS coverage on GL-Class applications. This strut is listed for the front left or right side, so confirm the original side and mounting style before installation. Inspect air lines, fittings, and related suspension components for wear or contamination during replacement. After installation, perform ride-height calibration and system checks according to Mercedes-Benz service procedures.
