Focus Auto Parts Air Suspension Spring P/N:Q4007
Focus Auto Parts Q4009 rear left air suspension spring for the 2012-2018 Mercedes-Benz CLS550 and other vehicles supports the rear left corner of the car with air pressure.
A rear corner that sits low, uneven ride height or a car that leans to one side can mean this air spring is worn, though the air compressor or a ride height sensor can be behind the same signs.
The 2014-2018 Mercedes-Benz CLS63 AMG S and the 2015-2018 Mercedes-Benz CLS400 also take this spring, along with many other Mercedes-Benz models. If your car is not one of these, look up its year and model in the "Vehicles it fits" section. A car takes one spring on each side of the rear axle. This listing is the rear left one, so the rear right is ordered separately, and the two are normally replaced together.
Does the Focus Auto Parts Q4009 fit the 2012-2018 Mercedes-Benz CLS550?
Yes, Focus Auto Parts Q4009 is the rear left air suspension spring for the 2012-2018 Mercedes-Benz CLS550; for other cars, look up the year and model in the "Vehicles it fits" section.
Is the Q4009 air suspension spring for the rear left or the rear right?
Focus Auto Parts Q4009 is made for the rear left. The rear right takes its own spring, which is a separate part.
Is the Q4009 a coil spring or an air spring?
This rear left part is an air suspension spring. It supports the corner of the car with air pressure instead of a coil spring.
What signs can a worn Q4009 rear left air suspension spring cause?
A sagging rear left corner, a ride height that differs from side to side or a lean to one side can mean the spring is worn. A shop can test the air system if you are unsure.
Will the Q4009 rear left air suspension spring work on the 2014-2018 Mercedes-Benz CLS63 AMG S?
Yes. Focus Auto Parts Q4009 is listed for the 2014-2018 Mercedes-Benz CLS63 AMG S at the rear left position.
