Replaced the stock anti roll bar on the 2016 C Class (E450 chassis) with one of these. If you have an impact wrench, you can do the installation yourself. Watch the installation video on the manufacturer's website and make sure you're also purchasing the correct bracket kit (sold separately). Approximately 1.5 hours for installation, plus road test/calibration time. BEFORE installing any of these, (1) make sure the tire pressure is correct (2) make sure the RV load distribution is correct and (3) prepare to have the wheel alignment checked.
