I had a horrible experience with Rough Country. I bought their 4" kit around 5 years ago and within a year the springs had sagged so much that the rear shocks bottomed out over a dip on the highway, one shock came off and fell forward, dragging on the pavement until I stopped and realized what had happened. It had ripped the upper mount clean off. I measured the distance from the bump stops to the "extenders" they give you to bolt onto the axle and it was at most 2". That being said, the springs were so stiff that I only bottomed out a few times that I can recall. I called them and got 4 new springs as warranty replacements and when they got here I was charged $150 cash on delivery for shipping fees, after being told that they would take care of it. I sold the springs and never looked back. Overall, a horrible experience. In the Jeep aftermarket industry, you almost always get what you pay for.
