Team-
I am thinking of swapping gears on my F250. We are going from a 4000lb dry weight, 21' camper to a 5500lb dry weight (6500 all up planning factor) Wild Wood 28'. I am currently running 3.73s (factory). I just ordered an addco rear sway bar, (truck had none), and am upgrading the shocks from factory Ranchos to Bilstein HDs. The truck has 71,000 miles on it. I am running 33" tires (3" taller than stock). Factory tow rating 9200lbs. I am considering 4.30 or 4.56s. The factory tow rating with 4.10s is 11,200lbs. I think the 3.73s will do it, but I live and camp in mountainous areas, plus the little V8 needs all the help it can get in general. Any thoughts on brand of gears, good diff shops in the central Tennessee area? 4.56 or 4.30? I don't think it will make much difference, but we have decided to keep the truck for a while, and in the mountains I think you need as much gear as you can get, and I am leaning towards the 4.56s. I had them in a 2wd F150, and they were great. I have the factory limited slip. Do I need a new carrier in a D60 and Ford 10.5"? WHAT I DO NOT WANT OR NEED IS ADVICE TO UPGRADE TO A V10, DIESEL, WHATEVER. Thanks for your time.
