Hi all, I have a ZJ running on 2" spring spacers and 245 75 16's. My front control arm bushings are shot. I was thinking about replacing with stockers but have heard jk rear uppers are a common upgrade for those running 3+ inches of lift. Can I run these on only 2" of lift? If it makes a difference I was considering stacking my stock isolators back in for the extra .25-.5". Thanks for the help.
