Keep the front of your Mercedes-Benz riding on a fresh air spring with the Arnott Industries Air Suspension Strut AS-2820, a complete, pre-assembled front air strut. It is a direct-fit replacement for many Mercedes-Benz models with AIRMATIC and without 4MATIC, among them the 2007-2011 Mercedes-Benz S500, 2011-2013 Mercedes-Benz S350 and 2010-2013 Mercedes-Benz S400. See the Buyer's Guide tab for the full list and engine details.
- Complete new assembly: This aftermarket strut is built with OE-quality components. It pairs a custom-valved shock absorber with a durable Continental ContiTech rubber air spring bladder.
- Multi-ply ContiTech bladder: The bladder is designed to hold air pressure for consistent ride height and performance.
- No lower isolator seal: The design leaves out the lower isolator seal, a component that is subject to failure on the O.E. strut.
- Protection and hardware: An aluminum can and a dust baffle partly shield the strut from debris. The strut is assembled with heavy-duty crimping rings, seals, O-rings and a bump stop.
The strut arrives pre-assembled for easier installation and plugs directly into the vehicle's electronic connector. Detailed installation instructions are available. It is designed and assembled in the USA. For best results, Arnott recommends replacing struts in pairs.
These signs may mean a front air strut needs replacing:
- a front corner that sags after the car has been parked
- an air compressor that runs more often than usual
- a bouncy or unsettled ride
Leaking lines, valves or a worn compressor can cause similar symptoms, so diagnose the air system before you replace the strut.
