honestly, the 241or, with a box 4 rocks is way overkill, even with 4.56 gears and 40s.
I rarely ever use low-low, 2.72x2.72=7.40:1 low range. I think once on ultimate adventure?
The 241or would be 4x2.72=10.88:1 low range.
Reason being, without a full manual shift conversion, we only have 1st and 2nd gears in any low range lower than 2.72. there is the option of putting the vss in the trans, but that is untested in our application.
a dually axle is 8-10" wider than stock full width, so around 77" wide up front. Dually 14 bolt is 72" so spacers on the rear to match would be needed. then run the deeper backspace hummer wheels. then thats a 8.5" wide wheel with 7" backspace, so your looking at a overall width of something like 86" wide. Thats where I am at with a 69" wide axle and 17x9.5" beadlocks on 4" backspace.
H1 wheels severely limits your tire selection.
cheap and easy is a stock width srw dana 60, and h2 17" alum wheels. thats about as narrow as i would want to be. (and i have run that combo.) my tow rig is setup that way, with 12.50 wide tires it is 80" wide outside of tire.
