Installation Notes

Verify the vehicle is equipped with AIRMATIC and confirm rear right placement before ordering. Match the model year and body configuration exactly, including the 212 body code note where listed for the 2010-2014 E350 application. Professional installation is recommended for air suspension service because system depressurization and calibration may be required after replacement.
