Review on nifeida Rear Left Air Shock Suspension Spring for Mercedes-Benz W211 W219 2003-2011 E550/E55 AMG/E63 AMG/CLS500/CLS550/CLS63 AMG/CLS55 AMG-Driver Side | 2113200725 2113200825 211320082580 Compatible by Russ Charmin

Works as it should but arrived with a dry rotted zipper securing trunk to underside of airbag which disintegrated on touch and failed to send the fixing clip securing top of airbag to body. I also had to sand down the bottom mounting tab that the screw goes through as it was too thick to fit between the bottom arms where it attaches. Had to have it fitted ASAP as the vehicle is not steered but note that you should not fit an air spring with these problems. Due to these shortcomings, the installation turned into a complex and lengthy installation. I hope the air spring holds up.
