I have a 6" suspension lift I want to put on my truck, which is a 2000 f350 crew cab, long bed. The kit I got came with 6" lift blocks for the rear, but I have read that the lift blocks will cause axle wrap. Also, these new lift blocks don't have bump stops like the factory blocks do. I like having the bump stops especially since I tend to load the back of my truck up pretty heavy on occasion. I don't have the money to sink into aftermarket rear springs, so are there any other options out there for lifting the rear, or should I just put lift blocks in?
