I have them and have used them a lot. I love them thay have saved me a lot of money on body work. Some people are worried about some thing geting stuck in the side bars but I dont see that happening I've used them all over and no problem and have slamed down on them verry hard and I'm verry happy with them. P.s. I have the ult ones he also did a 2" lift for me since I have a 2" body lift for free he is a nice guy.
