Alright guys/gals, Ive got 4.5" springs with 2" spacers right now on short adj. arms. My springs are starting to sag so Im thinking of replacing them and going long arms. My question is this: Should I replace the springs with more 4.5" springs and keep the spacers, or should I get like an XJ 7.5" from RE which I think would net me around 6.5"-7" in the front and use a ZJ front lift coil for the rear so that I get rid of the spacers all together? Also if I do option number two with the XJ coils, what size front zj lift coil will net me about the same in the rear? I know the stock springs are supposed to give 2.5"-3", so would this hold true with lift springs? Example: front 4.5" ZJ coils would net about 7"-7.5" in the rear?? Thanks for any advice
