Considering a New F250 or F350 6.2 which axle ratio should I get?
I'm looking at getting rid of my 2011 F250 diesel and getting a new 2013-14 250 or 350 6.2 L gas version of the same truck. What axle ratio should I get 3.55, 3.73 or 4.30? I know fuel economy will not be good regardless but I would like the best combo possible. I tow occasionally. Have there been any major problems with this powertrain?

More info needed. How much weight, how often do you tow? What kind of terrain towing (Mountains, hills, mostly flat etc). Will you daily commute in this truck? If so, how far. How about future plans? Bigger trailer, or 5th wheel in the future possible? No matter what, I wouldn't get less than the 3:73's, but that's just me. I don't commute in my truck. I don't actually have one yet I'm just trying to help so some of those on here that do can give you better advise. For myself, if I end up ordering one I'll have the 4:30's. better towing/hauling performance for what some on this forum have said is not much worse mileage. Hope that helps. Good luck,

Out of curiosity, why are thinking of dropping the diesel?

There are threads posted at a couple of sites I have been that showed the engine R's and speeds in the gears.
I have a 2012 with 4.30. It does fine with the 11.5K fifth wheel.
However if I had it to do over, I probably would have gone with the 3.73 and towed in 5th - amounts to about the same thing but I would have had the 3.73 for cruising.

The only choice for me would be the 4.30 ratio. I have 2 V10 F350s and both have the 4.30. I have a new F250 on order with the 4.30. With the 4.30 you can still travel 75 or 80 and at very low rpms for a gas motor. When towing a large load, these engines would do a better job with a 4.56, 4.88 or even 5.13. Gas millage will probably be better with the 4.30 anyway, just slow down a little. Alway get the lowest gear ratio ford offers and you are better off. We have a 12 expedition, the forth expy we have had. The first three all had 3.73 gears. Dealer talked me into ordering the 12 with the 3.30 ratio, because we don't tow with it. It is a dog compared to the first three. And gets the worst millage of them all. We love it, but the gear ratio sucks. It always seems to be lugging and downshifts way more on the highway. So even if you just haul a bag of groceries home from Wally World, get the 4.30, you will be glad you did. I would not even look at 3.73 geared truck with a gas engine. We also have a Shelby Raptor on order. It will be the 4.10 ratio, the only one offered, with a supercharged 575 HP 6.2 Ford engine. Should pull allright.

How does the 6.2 pull compared to the V10? And I take it you had the two valve V10, or did you ever have a three?

Get the 430 gears. I have both a 6.2 and a 3v v10. The v10 pulls harder off the line and the 6.2 outdoes the v10 at hwy speed passing. Not by much either way. My v10 has 4.10 and the 6.2 has 4.30 gears. Mileage is the same at 15 hwy in both. I have an intake and exhaust on the 6.2 which didnt make a noticable differance aside of the cool sound. I am not sure which motor I prefer.

I think you made the right choice. I guess you saw my other post comparing the two. The short answer for me is that the 4.30 wins ... if you tow enough to care about acceleration performance and you don't do lots of unloaded highway miles.
If you do care about highway unloaded mileage, 3.73 is better and as has been mentioned, 3.73 in 5th essentially equals 4.30 in 6th for steady state running on the highway so you don't lose really anything in towing highway cruising.
I have a similar commute and towing situation and the 4.30 is what I'll be looking for when the time comes.

I'm leaning toward a 4.30, but if towing in 5th with a 3.73 is the same as 6th with a 4.30 then why not go with a 3.73 so you would get a bit better economy unloaded as I would think that most people who get a gas version don't tow all that often anyway otherwise they would opt for the diesel?
