I am convinced this is a good choice for a rear end on my 51 1/2 ton with 350 and 700R4. Going to use 3:73 locker. My question is what is the advantage if any to center the carrier in the middle of frame? I have read some guys are cutting off the long axle tube on the one side and then using a short axle so that both sides are equal length. I have also read the offset is not enough to hurt anything. Anybody done this ? and what size wheels were you able use as far as width and offset and keep them inside the fenders ?
