I just put a 2 inch spring lift in my 01. It's on 31's. What I did notice. The rear axle shifted about 1/2 to 3/4 of an inch, the front moved a touch but not noticeable looking at the front of the jeep, I did notice the jeep feels different going down the road, it moves around a little more, but not bad. Overall I love the look and the ride is nice. I will fix the rear axle the off set will drive me nuts no big deal on that just a track bar..
