Hi everybody this is my first post as a new member hopefully I’m not covering a topic that has already been discussed.
I’ve got a 84 f350 drw 4x4 6.9idi
It currently has a Dana 70u drw axle in the back. I’ve done some research and it looks as though it has an axle rating of 7500# but the 4 ten ply tires are rated for 11200#. I’m not really seeing a point in the duals if my axle rating is so much lower. I mostly use the truck for pulling a horse trailer up the mountain during hunting season and moving some miscellaneous farm equipment around. The duals kind of suck sometimes as I don’t fit in the ruts, rocks get stuck in them from time to time, and if it weren’t for chains and a set of lockers it would be completely helpless in the deep snow/mud. I’m not seeing a good justification for the extra 400+ in tires when it lowers my fuel economy and doesn’t increase my load rating. I’m thinking about putting a srw behind it and maybe running 12 ply’s, or putting an axle that actually makes use of the extra rating from the tires. What are your guys thoughts on this and what axle recommendations would you have that wouldn’t sacrifice too much WR or locker availability.
By the way a previous owner converted it into a dually hence the 4x4 and I think it would make swapping back to a SRW simpler.
Thanks in advance
