Westar Air Suspension Spring P/N:AS-7090
Westar AS-7034 rear left air suspension spring for the 2007-2011 Mercedes-Benz CLS350 and other vehicles holds up the rear left corner of the car on compressed air. It is a new replacement spring, sold one per listing.
A rear left corner that sits low, a car that leans to one side, or air escaping from the spring can mean it is worn, though a leaking air line or a weak compressor can be behind the same signs, so find the cause before you replace it.
The 2005-2011 Mercedes-Benz CLS500 and the 2007-2011 Mercedes-Benz CLS550 are on the list too. Each car takes one spring at the rear left, and the rear right is a separate spring ordered on its own; the two sides are normally replaced together. If your car is not named here, look up your model and year in the "Vehicles it fits" section on this page.
