I'm gonna go out on a limb here and say no there will be no 4wd versions of this set up
heck I'm still a little baffled by the 1:1 4wd version its about as funky as it gets it works but dang they couldn't make it any more complicated lol
it just won't scale down the 10.2 diffs are just to big
the biggest issue will be finding a period correct body they only used this suspension on Ford trucks and a few years of the exploder
maybe that's the next new release lol
