I have. The perosn said that it can be put on by the home shop guy meaning you do not have to have a lift. he said he has them on his SHO and it helped out a lot. but they do need to be aligned by a pro. I think they would nice to put in. I have the sway bar in gradge that needs to be put on so since I am going under the car I was looking into them. The sway bar ones are the ones that I want to put in first, but I do not know how hard it is to put in. also that one has the swaybar link on it so that is way it is a box.
