i am trying to order my springs so that i can install my axels in the next few weeks (d60/14bolt) but i am having a tough time deciding on the right combination. my first thought was a 2.5 shackle flip and skyjacker 2.5 inch springs in the rear for a total of 5 inches. i am only doing the 2.5 shackle because my springs are worn and must be replaced regardless of what i do. in the front i will install 4 inch skyjacker springs (i will pick up an extra ¾ inches with my d60 and ¼ inch with ord heavy duty front shackles). i can even anything up with a zero rate - either front or back. my second thought was same up front (4 inch springs) and a 4 inch shackle flip in the rear with the 2.5 skyjacker springs. this is only an extra 1 ½ inches and as the first option i can use zero rates to even out if required. i will run a 36 or 37 and know that i will have to cut some metal. i am also straight on my steering geometry. i know this gets ask daily but these springs are expensive and i want to get it right the first time. anyone have feedback on my option 1 or option 2?
