AS-2820 is a new, not remanufactured, aftermarket air suspension strut for the front of the 2007-2013 Mercedes-Benz S-Class (W221 Chassis) with AIRMATIC and without 4MATIC.
This replacement strut, designed and assembled in the USA, features a new custom-valved shock absorber assembled with a durable new Continental ContiTech rubber air spring bladder and no lower isolator seal which is subject to failure on the O.E.
The strut is partly protected by an aluminum can and dust baffle to keep out debris and is assembled with heavy-duty crimping rings, seals, O-Rings and bump stop. This fully assembled air strut plugs directly into the vehicle’s electronic connector and eliminates fault codes.
