Arnott Europe has introduced front air struts for Mercedes S-Class W221 with Airmatic without 4Matic.

• AS2540 is a remanufactured OE strut that features a new rubber air spring bladder, from ContiTech, and an improved upper seal design using O-ring sealing technology rather than the original epoxy design.
• AS-2820 is a brand new high quality aftermarket air suspension strut for the front of the 2007-2013 Mercedes-Benz S-Class W221. It features a new custom tuned shock absorber and a CNC machined top mount made from aircraft quality aluminium. The Arnott strut is pre-assembled and includes a new air bladder from ContiTech which is protected by an aluminium can. The strut is assembled in the USA with Arnott's long lasting seals, new bump stop, heavy duty crimping rings, protective dust boot and a new check valve and airline fitting. The strut is backed by Arnott's exclusive Limited Lifetime Warranty.
