Product Details

Arnott AS-2450 is built as a remanufactured OE front air strut for Mercedes-Benz GL350, GL450, GL500, GL550, ML350, ML450, ML500, ML550, GL320, and ML320 front suspension applications. It is engineered for vehicles with ADS and uses an air-adjustable, progressive-rate design to restore front-end ride height control and damping response.

The Arnott remanufactured line focuses on rebuilding original suspension components rather than replacing the entire system with a generic assembly. For drivers searching for a Mercedes-Benz GL450 front air strut, Mercedes-Benz ML350 front suspension strut, or an ADS front air suspension strut for GL550 and ML500 models, AS-2450 provides a direct-fit service part with OE-style construction details.

Common Problems This Part Addresses

• Front suspension sag or uneven ride height
• Air spring bladder leakage
• Excessive bouncing or poor damping control
• ADS warning lights related to front strut performance
• Noisy or unstable front suspension operation

Installation Notes

Install on the front left or front right position only where the vehicle uses ADS-equipped air suspension. Verify the vehicle’s OE part number and suspension configuration before installation, especially on Mercedes-Benz GL and ML models. Because this is a remanufactured air strut, proper system inspection is recommended for air lines, sensors, and related suspension components during replacement.

Quality Assurance

AS-2450 is remanufactured and backed by Arnott’s Limited Lifetime Warranty. The rebuilt design uses OE-based construction details and a Continental ContiTech air spring bladder to support consistent suspension performance on Mercedes-Benz GL350, GL450, GL500, GL550, ML350, ML450, ML500, ML550, GL320, and ML320 front applications.
