I am going threw the same delema, i want to install a 7-mgte and build it to 400-500hp, so i want an axle that can handle that kind of power, So far from what I have read in the past people running this set up end up breaking a ring and pinion set or a carrier not the axle shafts them selves, so do you think a v-6 and a high pinion would be up to the task of that much power? because I think with chromo longs and front range's full floater kit I would be ok axle shaft wise. Also is it worth it to go full width? I know it looks cool and gives you more flex, but the whole point of a toyota is it size and wieght.
