don't get the sahara if you plan on taking it off pavement, the axles are crap dana 30 variants.
the wranglers come with d44 variants, but it shares the outers and C's of the d30. the real difference is the ring and pinion diameter (stronger), and i think the axle shafts are stronger.
if i came across a built sahara on the trail, i'd laugh. there is no sense in building a d30, they are garbage. pretty much only good for rolling under the truck.
what did you end up getting?
professional grade '02 nissan frontier rock crawler, and a 325 with a few add-ons.
