I was jsut going to write this for people that are wondering about getting a leveling kit, and the wear and tear it will put on your truck. My father has had a 2.5 daystar leveling kit on his 2004 f-150 for about 55,000 - 60,000 miles and he has not had one problem, with boots or anything. I was just writing this to let people know, because i know people wonder if it is safe or ok to put on your truck..
