Work as expected
I ordered the pair of air bags as my wifes 08 R320 was sagging on one side. After replacing the car was still sagging. Replaced the other side and the car is completely level. Replace in pairs. They are very easy to replace, about 30-45min per side. Be careful to watch how the brass fittings fit together and also how the white retaining clip is used to hold the bag to the top of the bag attachment area. My wife and I both feel the car rides better on these bags.
