Product Overview

The air suspension strut, OEM number 2133202338, is the front left Airmatic strut fitted to the Mercedes-Benz E-Class, W213 and S213 chassis, 4MATIC applications, model years 2017-2023, and the Mercedes-AMG GT-Class, X290 chassis, model years 2018-2026. Since this strut spans both a mainstream sedan/wagon platform and a performance sports car sharing the same suspension architecture, it's a valuable part to stock for anyone servicing these Mercedes air suspension systems.

Worn or failing units typically show up as the vehicle sagging or sitting unevenly, a rough or bouncy ride, an air suspension warning light on the dashboard, or an audible hissing sound from a leaking air spring. GSK Auto manufactures this air suspension strut to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this strut is specific to 4MATIC applications with Airmatic, and left/right struts are not interchangeable, so it's worth confirming drivetrain, suspension type, and side before ordering at volume.)

What Is an Air Suspension Strut?

Function: The air suspension strut replaces a traditional coil spring and shock absorber with an air-filled bladder and integrated damper, allowing the vehicle's ride height and damping characteristics to adjust automatically based on load and driving conditions.

Working Principle: An air compressor fills the strut's air spring to maintain the correct ride height, while the integrated damper adjusts damping force based on road conditions and driving inputs, delivering a smoother, more adaptable ride than a fixed mechanical suspension.

Importance: The air suspension system is central to ride comfort and handling on both the E-Class and the AMG GT, and a failing strut affects not just comfort but also handling stability and, if the air spring leaks badly enough, can leave a corner of the vehicle sitting low or uneven.

Common Failures & Signs: Air spring bladder wear or cracking causing air leaks over time. Vehicle sagging or sitting unevenly, particularly noticeable after sitting overnight. Rough, bouncy, or harsh ride quality compared to normal. Air suspension warning light on the dashboard, sometimes accompanied by an audible hissing sound.
