Allright. I want to do the 56" spring swap for the front. #1 I need to know what this spring comes off of. I've heard off of the rear of the 1st gen. of GM IFS trucks. Is this true? and should it be off of a 4x4 or 2x4 version? B. I need to net 8" of lift. I've read the stock 56" rear springs give you 4" of lift swaped into the front. So, if that is correct, I need a 4" lift spring from a 88-98 gm truck. If this is not correct , somebody please point it out. #3. How far forward is this going to push my axle? No fender triming yet, will if needed. is it going to push it way out of center of the wells? #4. I know you have to run cross-over, but I have not heard anybody say if they run hy-steer. Just wondering how much forward can the axle be moved with out the drag-link making contact with the hy-steer tierod?
