You should never stack spacers or blocks :bangit:I got a stage 1 stacked w a spacer level.
it rides like ****, but that additional top 1.5" is the biggest 1.5" ive ever seen.
I also double stacked a 1.5" block on top of my PC. If you got stage 1. Either go a head and get a 5.5" rear block or get a 4" then stack. That 3" block stage 1 comes with is weak.
(side note) i dont off road it. I wouldn't go off road with rear blocks stacked
