Product Overview

The air suspension strut, OEM number A2133202001, is the front right Airmatic strut with ADS (Adaptive Damping System) fitted to the Mercedes-Benz E-Class, covering the W213 sedan, S213 wagon, and C238 coupe, model years 2016 onward, including the E180, E200, E220d, E250, E300, E300d, E350, and E350d. This is the companion part to the front left strut used on the same platform, and since both sides are commonly needed together for a complete air suspension repair, it's a part worth stocking alongside its left-side counterpart.

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 is specifically the front right strut for vehicles with ADS, and it's commonly needed alongside the corresponding front left strut (A2133201901), so it's worth confirming with your customer whether they need both sides.)

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 Adaptive Damping System electronically adjusts damping force in real time based on road conditions and driving inputs, delivering a smoother ride than a fixed mechanical suspension. This strut ships complete with the air spring, shock absorber, and electromagnetic control valve.

Importance: The air suspension system is central to the E-Class's ride comfort, 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.
