i know i will get a bunch of crap about the axle setup but i like it and had no issues. have km2 35's now and am switching to pitbull rockers this winter. wanted to know what people with similar set up thinks bout the 37's and 39.5's. have power and gearing already. it is a trailer queen.
the tubes will not handle anything over a 35in tire. the dana 30 you'll snap shafts and ring gears and bend the Cs. also the hubs and ball joints will not like bigger tires. the 35 will just kill it self with 37+ inch tires either bend like a pretzel or just blow up. if your running 37+ inch tires get tons and do it right
