Im getting the 4" Shackle Flip from Echobit for christmas to get rid of my block in the back. Im also getting a set of front and rear 1" Zero Rate springs from OffroadDesign. Im going to need some help from people who have installed this stuff. What tools do i need? How many Jacks/stands, how hard is it. Stuff like that. And even a little better detailed instructions than echobit's, it kind of confuses me. Thanks alot.
