I found a set of 5 2009 rubicon wheels and tires bf goodrich with 15k miles. I get 5, the springs, shocks and front bumper. First will this work on mine? And would I have to modify anything else since it is supposed to give me the guy said about 2" of lift? I am looking for something to help me on the trails a little better, little better tire than I have and the clearance from the springs and bigger wheels. Let me know what you think. Price is about $1000
