So, when was the last time YOU checked your nuts and bolts on your suspension? I did a 4/6 drop a short while back and tightened everything good and the next week retightened again. I went out tonight and threw a wrench to the spring ubolts and I got about 3 full turns at all four corners. I would highly recommend you check yours too if you have had the factory ubolts off anytime in the past. Thank God the nuts they send in a Belltech kit have nylon locks on them or else they probably would have backed all the way off.
