I'm on 37's...but with a axle swap(fzj80 axles) and it's a trail truck, not a (and i hate this word) "overland" truck. I manage to get about 10mpg. Keith(Rovertracks) hasn't marketed a d2 kit "yet"...
some guy's are running the new the ashcroft front cv's, but I'm not sure about more than a handful on 35's. They'll fit in the wheel well, but you'll need at least 4.11 in the diff's to have any ability to out run a school bus. A 1.4 hi gear with 3.54's would work well. I have a 1.6 hi-gear and that's too much. A 1.4 with 4.11's would probably be best with my set-up...driveshafts are a must...
quick picture add...
the 110 is stock,as is the D1 so the D2 isn't the "high" as in monster truck height...and the driver side tire is flat on the d2 because my beadlocks started leaking...for no apparent reason
