Detailed Product Overview

AS-3522 is engineered as a new replacement for aging front suspension components on the Mercedes-Benz GLC-Class X253 platform. It retains the comfort and auto-leveling function expected from air suspension while replacing the original shock with a brand-new unit calibrated for balanced control and ride quality. The assembly uses a black boot, upper stud mount, lower clevis mount, and an internal hydraulic damper with progressive spring rate characteristics.

This part cross-references OE numbers 2533200401 and 253320800180 for the same application. Search terms such as Mercedes-Benz GLC300 front right air strut replacement, GLC43 AMG air suspension strut, and GLC-Class X253 front right air spring strut all point to this application.

Common Problems This Part Can Address

• Front-end sagging or uneven ride height
• Air leaks from a worn bladder or aging seals
• Excessive bouncing, harshness, or reduced damping control
• Suspension warning messages related to air strut performance
• Loss of auto-leveling function at the front right corner

Installation Notes and Tips

Verify the vehicle’s chassis and position before installation. This AS-3522 is for the front right side only and is intended for Mercedes-Benz GLC-Class models with air suspension. Inspect the air line, fittings, and related suspension components during replacement to help prevent repeat failures caused by worn supporting parts.

After installation, the suspension system should be checked for proper ride height, leaks, and fault codes. A professional alignment is recommended whenever suspension components are replaced.

Quality Assurance

Arnott designs and assembles this air strut in the USA using new components, including long-lasting seals, O-rings, bump stop, heavy-duty crimping rings, and a new air fitting. The AS-3522 is a new replacement part, not remanufactured, for service on compatible Mercedes-Benz GLC-Class applications.
