Arnott Industries Air Suspension Strut P/N:AS-2821
The Arnott Industries AS-3898 front right air suspension strut for the 2012-2018 Mercedes-Benz CLS550 and other vehicles is a complete strut assembly that holds the air spring and shock absorber in one unit. It is brand-new and built from OE-quality components to replace a worn OE strut.
A worn air suspension strut can let the front right corner sit low after parking, make the air compressor run longer than usual, or leave the ride bouncy. With the engine off, look at the air spring sleeve in the wheel well for cracks or chafing. A leaking air line, valve block or compressor can also make a corner sag, so find the leak before you order. For best results, replace the front struts as a pair; this listing is the front right strut only.
The 2012-2018 Mercedes-Benz CLS550, the 2015-2017 Mercedes-Benz CLS400 and the 2010-2016 Mercedes-Benz E350 are among the cars it fits as a direct-fit replacement, one strut at the front right, when the car has 4MATIC, AIRMATIC and ADS. It is not suitable for European Avantgarde or AMG models. Driving a Mercedes-Benz not named here? The Buyer's Guide tab shows whether this strut fits it.
