I'm getting ready to tear down and rebuild the K5. I was not planning to do a spring swap but after seeing the flex with 52's and 56's I am considering going that route. I don't want more lift then I already have. I have 3" front springs and 4" rear springs. I also don't want to mess with the wheelbase. If I do this I will do a flip in the rear. What I need to know is what all is needed besides the springs, rear hangers, and new u bolts and will this move the front axle forward? Also will the rear axle stay in the same place? I read the write up on here for the front swap but looking for any info I can get. Also on the front springs should I keep the overload stock, cut it or remove it? TIA.
