Arnott Industries Air Suspension Strut P/N:AS-3123
Give the front left corner of your Mercedes-Benz a new air spring and shock absorber in one assembly with the Arnott Industries Air Suspension Strut AS-3594. This complete strut is built with OE-quality components and replaces the OE strut on Mercedes-Benz models equipped with ADS Plus, including AMG versions. It fits many vehicles, among them the 2019 Mercedes-Benz GLS500, 2017-2020 Mercedes-Benz GLE43 AMG and 2016-2020 Mercedes-Benz GLE63 AMG. Arnott recommends replacing struts in pairs for best results, so plan to replace the front right strut as well.
Signs this part may need replacing: a front corner that sags after the vehicle has been parked, an audible air leak at the strut, or an air compressor that runs more often than usual. Other components in the air system can cause the same symptoms, so diagnose the cause before replacing the strut.
This strut fits ADS Plus-equipped vehicles only. See the Buyer's Guide tab for the full vehicle list and engine details.
