Ahhh rock crawlers... $$$$$$
You looking to build a buggy or street/trail rig? I've helped run calc's in the past on high travel off road suspension designs if you're looking to go the complete custom route.
Before my neighbors forced me to get rid of my jeep I had planned on HP D60 front and D60 rear, with 8 lug - 15" wheels running 42" Iroks with 4 link front and rear and full hydro steering...
I've still got the custom 15" wheels w/ 2.5 BS, a couple of 1410 - 32 spline yokes, and HP D60 Sky Manufacturing high steer arm it's very slick, if you're interested... I gave away everything else including a twin sticked NP205
