I know they are 3500lb axles and it's 76 1/2" between the wheel wells as for the brakes i don't remember but i will check when i get home from work in the morning. I used it to haul a rhino and a teryx both with long travel and they fit on there no problem. And they are 5 lug wheels.
yea it's going on there today or tomorrow i just thought i'd try here and see if anyone here could use it before i put it there and had to deal with CL.
