Arnott Industries Air Suspension Strut P/N:AS-2581
Help keep the rear left corner of your Mercedes-Benz at a consistent ride height with the Arnott Industries Air Suspension Strut, part number AS-2822. This new, fully pre-assembled rear left strut is a direct-fit replacement for many vehicles, including the 2007-2011 Mercedes-Benz S500, the 2009-2014 Mercedes-Benz CL550 and the 2011-2013 Mercedes-Benz S350, for vehicles with AIRMATIC, both with and without 4MATIC.
This complete strut assembly is built with OE-quality components. It pairs a custom-valved shock absorber with a durable Continental ContiTech rubber air spring bladder. The design also leaves out the lower isolator seal, which is subject to failure on the O.E. strut. An aluminum can and a dust baffle partly protect the strut from debris. The assembly uses heavy-duty crimping rings, seals, O-rings and a bump stop.
Signs this part may need replacing include the rear left corner sagging after the vehicle sits, an audible air leak near the strut, or the air compressor running more often than normal. Diagnose the cause before replacing. For best results, Arnott recommends replacing struts in pairs.
See the Buyer's Guide tab for the full list of applications and engine details.
