Quick facts
- Part: Arnott Industries AS-3898 air suspension strut
- Fits: the 2012-2018 Mercedes-Benz CLS550 and other vehicles
- Position: Front right
- Condition: New
A sagging corner, a harsh or bouncy ride or air leaking at the sleeve can mean a strut is worn. Other air system parts can produce a similar sag, so find the cause before replacing it: compare that corner's ride height with the other side on level ground, engine off, and leave air system testing to a shop. For best results, replace struts in pairs; this listing is one strut, and the front left is a separate part.
