Product Details

AS-3005 is built for front suspension service on Mercedes-Benz GL-Class models that use AIRMATIC but do not use Adaptive Damping System (ADS). Arnott AS-3005 is assembled in the USA and uses a progressive spring rate, spring-assisted air ride construction, and a hydraulic internal damper to restore ride height control and road isolation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

For buyers searching for a front air suspension strut for Mercedes-Benz GL450, GL500, GL550, GL320, GL350, or ML450, AS-3005 provides a direct replacement format with OE-style mounting points and air suspension functionality. The part number AS-3005 is also useful when verifying service replacement against original Mercedes-Benz references.

Common Problems This Part Can Address

• Front-end sagging from a leaking or worn air spring
• Uneven ride height at the front of the vehicle
• Excessive bounce or reduced damping control
• Air leaks at aging seals, fittings, or bladder material
• Ride quality loss on high-mileage AIRMATIC suspension systems

Installation Notes

Confirm that the vehicle is equipped with AIRMATIC and not ADS before ordering. This front strut uses a clevis lower mount, stud upper mount, and integrated air fitting, so matching the original suspension configuration is important during installation. After replacement, inspect the air lines, compressor operation, and related suspension components for wear or leaks.

Quality Assurance

Arnott manufactures this new air suspension strut with long-lasting seals, new O-rings, a ContiTech multi-ply bladder, and heavy-duty crimping rings. AS-3005 is assembled in the USA and built as a new aftermarket replacement for front suspension service on the listed Mercedes-Benz GL-Class applications.
