Fun while it lasted
Very easy to install, I love the air suspension but after a solid month they both blew when I jacked the car up to change the transmission fluid on my 07 CLS550 I'm disappointed but it was a smooth ride while it lasted.

I will recommend 1Aauto to my family, and friends.
1A Auto is the place to shop when you need OEM parts for yourcar. Also the price is good for the parts, and warranty also. If installed properly.
