stuff a 8.9" JK R&P into that rear 44 housing and wheel the snot out of it.
If you twist a shaft stuff some alloys in there then. The jk ring and pinion is huge and Is rated for 5300+ ftlbs of momentary torque vs a Dana 60 35 spline at 6000 and 30 spline at 5500 and a std Dana 44 at 3460 ftlbs Having the three side by side the jk pinion is just a hair smaller than a Dana 60 pinion all in the same ratios. now im not saying the JK R&P is everything but when we are all sitting here complaining about issues with our rear dana 44 R&P's and that being what typically breaks and then looking for a 5 lug or 6 lug alternative that is the same or simialr width with minimal housing stregth gain in some cases then it might be worth a second look.
I know that now after a year+ i and others have now pushed the JK R&P in scout rear housings and cherokee chief rear housings as well as in several front end projects for broncos, scouts, waggys all rigs are pushing 35's or larger mine is on 37's and has run 38.5's but i also went with 35 spline shafts. all of the rigs listed have detroits, ARB's or Ploks and see plenty of trail time between las vegas, rubicon and moab and none of us has had a R&P failure since doing the upgrades. we are all running healthy v8's, a couple guys with 401's a few with ford 351's and one with a 392 powered scout, a twisted shaft here or there but after alloys that seems to become a thing of the past also.
now the discussion shifts to housing and tube strength
