I look at it the other way. my 4 post makes it easy to do anything. I jack it up with the air jack and I have a table under it when I'm doing the brakes. then when I want to work on my race car it's sitting at ride height and I can check and do anything. check 4 Link, string line it. mine is a bendpak 14K.I got that one because it's wide so my 1 ton dually can drive on easy. it's probably a little more money with the jack but I like the piece of mind to that I don't worry about anything happening that it could fall off.
