Hey guys I'm back. I'm hoping to do the work I mentioned in a preveuous post. I am looking at replacing my leaf springs on the rear and the coils on the front. I noticed that my spings are startig to fan out and are starting to show gapping in between leafs. I want to lift the body up so I can put a bigger sizw tire on. What I have is a 3 leaf with an overload and a 2" block under the spring. The replacements that I found is a 4 leaf with an overload. What I need to know is do I need to loosen the bed any to do aligning and is the 2" block a stock part of the suspension? What else should look for while I am working on the springs?
