With there are four axle ratio choices with the SRW and diesel. I have no idea which is better.....or for what reason. Any input? See below.

i always like to assume the most expensive option is the best one which i will end up wanting, even if i dont need it.

With the load you will be towing, you definately want the 3.55; and you also want the Locking Rear End for traction on the ramp. (Since I know this won't be a daily driver for you; the fuel mileage is not a concern for said use.)

Since you are looking at 4x4, you will have that in reserve, but there is no advantage to a non-locking axle.

Are you going to send it off and have it changed into an X?

Personally I like the 4.11 gearing for towing at a minimum. Especially towing heavy loads, and a locking/positraction differential is a must. The lower gearing provides for great torque multiplication.

With a 5 and 6 speed transmissions of today, the rear gearing at highway speeds in inconsequential.

Currently I have 4.88 on one vehicle, & with the 35" taller tires on the truck, the final drive ratio is around 4.20-4.30, and 4.56 on another tow vehicle.

I tend to agree, but it looks as thought it may not be available.
(Remember, both the front and rear gears need to match in a 4x4, but Ford knows that.)

The 3.55 is more of a mileage gear than a towing gear. But the new Diesels have a lot more power which can and probably does make up for that.

IF you plan to go to bigger wheels and tires, you most certainly will want a 4.11 gear set. Or at least a 3.73. For these you may have to special order...
... or you can change the gears down the road. It's not a major project. Just gear swap changes in both pumpkins, and some computer adjusting of the torque management and transmission shift points.

I have this on both my 11's... F250 and F350. You will find the locking diff to come in handy. Yesterday on one of the muddy jobsites I pulled out 2 1/2 tons..a Tundra and Z71..The Tundra was a 2wd..but was blocking the 4wd Chevy....I have some better All Terrain tires..locked it in 4 hi..pulled the knob towards me..not even low..and slowly pulled out both of them at the same time out of the mud without slipping...way better than both your posi wheels spinning and one in the front.. What you want is to order posi..and locking differential..and the stock 20's that came on the 250 was Michelon which is a good all around tire that you will see about 45k out of...the BFG's I have on the 350 are more aggressive and slightly louder at hwy speeds..but work in my application well..Good luck. Jeff


3.55 gears are the tallest you can get...unless you get a dooley.. Ive always had 3.73, and 4.10's..but the new trucks have way more refined power and torque and are still better than my 08 and 10 dooleys with the taller gears..plus mileage is way up..especially when towing.. I just came back from towing a boat from MS to FT. Pierce FL and I averaged 10.2 mpg at and average 0f 72mph..wheres before I was getting 8.1..at 70mph..and oil change intervals are slightly longer even with the dpf fluid..savings all the way around..

Either gear ratio WITH the electric locking Diff. My guess is (have not researched yet but the Dodge Power Wagon is like this) That when not electronically locked in the rear is a limited slip diff.

I tow heavy with 3.42 gears and upgraded to 33" tires and love them. No problems, plenty of power, plus better fuel economy.

If you are lifting your truck and installing 37" tires or larger you will need to change your ratio anyways so again either ratio will work.

Stock tires, either ratio will work good

BTW, the new Ford does have traction control

I have spent hundreds of miles behind the wheel of my friends 2012 F 250 lariat. NICE TRUCKS! I am Still a Ram/Cummins guy but WOW, what a difference from his 06 I used to drive around!

Enjoy your new truck!

My wife and I test drove the F350 single wheel drive, and then just I drive the F450 dually back to back yesterday. Both trucks are crew cab, long bed, diesel 4x4, ride really nice and have great power. She liked the look of the 450 with the wheel flairs but not the F350 without the flairs (LOL).

I think the dually will be too much truck for us as we really don't tow that much, we like to go to the snow once in awhile, and our nanny would drive this vehicle with our boy. It's also harder to wash, hard to park.....and folks say dually's are not great in snow.

The F350 SRW is juuuuuuust enough truck and as I believe our towed load is somewhere between 13,500 and 14,000 (and with the addition of weight distribution hitch to my trailer) we will be under the rating. Easier to wash, easier to park, easier for everything........tires, rims.

Good call on the long bed too Norty. It's an unquantifiable difference towing, but the wheelbase also "makes it better."

Jimbo going to hook you upon rims? Make sure you get some tires with large white letters! It's all the rage. :D That way it will match all that chrome on the front!

Do you have EoH on the trailer already?
Also, eyeball the numbers on the hitch receiver itself when you get your truck. I all but guarantee that you can buy a stronger one.

Also, what about the Ex? I bet it will do well on eBay.

Yes I have Electric over Hydraulic brakes on the trailer. The factory hitch has the same sticker on the F350 SRW as on the Dually F450 and rated at 17,500 weight distributed and 8,500 carry.

There is a big difference between a tongue rated hitch for 18k gross and the stock hitch rated at 8.5k
The weight distribution is relatively the same because they are both pushing close to the max that a frame mount should use (also the 18k plus 8k truck weight is at 26k which is max weight before some states require a class A license.)

Dont forget your tow is no stronger than its weakest link.
A ball mount and ball equal or greater is also needed. http://www.curtmfg.com/index.cfm?event=prodetail&id=143&categoryid=47

Nothing as ironic as seeing a guy brag about his upgraded hitch only to see an 8k 10" drop mount :angry-smiley-044:

I wont say, dont do the WD hitch either but u just dropped that much on a new truck and sounds like will be towing a pretty big rig so dont skimp on the hitch components.

Unless you are towing some huge cabin cruiser or constant mountains, I am not sure the lower profile of a well balanced boat will justify the sway control needed on high profile, top heavy box trailers.

Yep, like Jass said, you will really like the truck. The Sync is great. I use the weather update all the time here. Shows radar and everything. Very cool here in the mountains. You can watch the storms when travelling. Lots of "gadgets" to learn.

Oh yea, the sway control is really cool also. It WORKS.

These are the stickers on the hitch and truck door area. It is the same hitch and sticker on the F350 Dually, and the F450 Dually. The truck included an option that boosted the GVWR to 11,500lbs, so does that also boost the towing capacity from the stock 14,000lbs? So confusing......also there is no GCWR on the sticker. :angry-smiley-038:

If you have an iPhone with songs loaded on it, you will find that your songs will start to play automatically via bluetooth audio every time you start your truck and your phone pairs up. There is an option for "Autoplay" that you can turn off but it will not stop the problem. To prevent Sync from starting music on your iPhone when it pairs, you have to have your system input set to "Line In" and remember to reset it to "Line In" if you ever hook up via bluetooth audio or USB to play tunes off your phone. Otherwise, Sync is great.

The increased GVWR mainly helps cover your azz if the truck was to get scaled by DOT. It is pretty easy to go over the 9900# rating on older trucks so 11,500 is nice. The 11.5k is apparently giving owners in certain states heartburn the way some laws are written conerning vehicles with a GVWR over 10k

Your tow capacity right now is limited by the hitch. Using the first picture; You have a 2.5 receiver which values are noted by the left table. If the 2" reduction sleeve is used, even lower values on the right apply.
Non-WD, the most you are rated currently is a measley 8,500# IF a 2.5" ball mount is used. Get a stronger hitch, ball mount and ball as suggested earlier to tow heavier loads.

(cheap and ignorant; these OEM brag huge weights but install substandard hitches when a properly rated hitch would probably cost less than $100 to the mfg )
