Arnott Industries AS-2820 front air suspension strut for the 2007-2011 Mercedes-Benz S500 and other vehicles combines an air spring and a shock absorber in one assembled unit. The design has no lower isolator seal, which is subject to failure on the original strut.
- Custom-valved shock absorber with a hydraulic internal damper
- Multi-ply Continental ContiTech rubber air spring bladder holds air pressure for consistent ride height and performance
- Aluminum can and dust baffle partly protect the strut from debris
- Strut is assembled with heavy-duty crimping rings, seals, O-rings and bump stop
- Fully assembled air suspension strut plugs directly into the vehicle's electronic connector and is designed to eliminate fault codes
