I have just about gathered everything I need for the lift for Buster(M1009), except shocks. Those will come next week. I'm lifting the truck to clear 35/12.5/15's. For the front I have Tuff Country 4" lift springs with 1" Zero Rates. On the rear, we are doing a shadetree shackle flip and keeping the stock springs. I understand that the flip should net 4" of lift. My question is how much should I lift the rear to keep it level? With the diesel, and stock springs all the way around, it sits level if not a little a$$ high, which is not typical for a Blazer. I am a stickler for doing things right the first time around. So would I be better off lifting the rear the same 5" or going 6-7"? To get 5", I would do the flip+Zero Rate. Otherwise, I was thinking about a flip+drop shackle to get an additional 2". I'll also be using shims to keep the pinion angles correct front and rear. Thanks for the help.
