I want to torsion crank my truck (99 Expy. E.B. converted from air) I got underneath and noticed that the drivers side has about half the threads showing than the passenger side. I would like to re index the drivers side so I can get maximum lift out of this mod. how do I do it? has anyone ever heard of getting MORE than two inches of lift? I read that about 4 revolutions is equal to 1 inch of lift, I would bet there is more than 8 turns on the pass. side, is what I read accurate? does this require me to have an alignment done after I lift the front and back and get new tires? (keeping the stock 17's) assuming the lift is 2 inches in the front, with a 17in wheel what can I fit without rubbing at lock? 315/70? 315/65? 305/70? 305/65? what if I can get 3 inches out of it? the stock running boards are already off.
