Installed on a 2002 Ranger 4x4 with no problems, about 20 minutes. 1500 pound setting. had very little impact on ride height, maybe an inch or so, and had no impact on ride quality, still very good. PS I have road tires that have the same load capacity as my old LT tires but with better handling the off road handling is a little worse. I don't know if it will hold the extra 1500lbs as advertised but just wanted to help load something heavy like in the past without lifting the front end like an old drag car! So far, so good!
