For the fellas at Off Road Design: I have an 89 K5 that is stock and a daily driver. I want to lift it 4" Suspension lift. From what I hear the shackle flip kit is the way to go. What I want to know is what all I will need to keep this machine riding as good as it does now but making it bigger. Shackle flip kit, new front leaf springs, what else??? If you guys have everything I would like to buy it all from one place. Thanks guru's..
