Allright another set of questions regarding 56" spring Swap out back. 1. What year and model trucks had 56" springs? 2. With stock 56" in place of my 52" and a shackle flip (sides swapped), how much lift should I expect the 56" springs to add on top of the lift allready gained by the flip? If any at all. 3. With this same setup, what will happen to my axle location? (move back or forward) This is keeping the spring correctly installed, not backwards. Thanks for any help. I'm trying my best to get this as right as possible on my first pass and everytime I search, I get so many conflicting reports. So I'm sorry for the repetative posts for you oldtimers.
