2 valve V10
I have 3.73, have thought about going to 4.30, but at what cost?
If I could buy axles I could do it myself, but I don't think I want to tackle a gear swap.
Has anyone had there gears changed from 3.73 to ? and what cost and how do they like them?
Thanks
Skatttracker2,
I called the local Ford dealership and they quoted me 3500.00 dollars to change gears. The cost is that high in part because I have a 4X4 and that means changing two ring and pinions. I'm fairly handy mechanically, but after asking many questions I don't think I'd ever tackle that task.
I found on the flats I get better mileage by locking out overdrive and running about 60mph.
My Truck scaled empty with full fuel, my wife and I in it & the fiver hitch installed at 6,940. My pin weight loaded was2300lbs.
On the flats here in Illinois I get low 9's to low 10's for miles per gallon. They told me my traile was to heavy for the truck too. But I have been very happy with it.
Hope this helps you. That engine is a work horse.Forgot to add, get a transmission guage. get something that plugs into the OBD port. I have one that is inst in the test port and I have a Scan guage that plugs in there is a 40 to 45 degree diff. My temps are fine as long as I'm not in the mountains. If you are getting much over 240 it might be a good idea to pull over and let it cool. Change fluid if it gets burnt look. I normally change mine every couple years as a precaution. But that is just me, fluid id cheaper than Trans.
Also I had 700lbs to spare before being over on truck GVW, but was no where near over axle ratings.
Forgot to mention mine is a SRW, nota dually
Good Luck : Hope I helped

Judgerr,
What's up with another temperature gauge for the transmission? Isn't the one that is already in the truck enough? Do I need to monitor it more closely than is possible with the stock temp. guage?
Thanks,

I pull a 9000-9500 lbs 5th wheel camper with my 2002 F350 4x4, at, 3.73 gears with a 2 valve V10. I also will pull my boat behind it at times. I live in Minnesota, so pretty flat. Truck does great around here. When I get out into the Dakota's and start pulling larger hills on the freeway, it will struggle to maintain 70 mph unless you really get into it, but does pretty well.
I have towed my camper into Yellowstone by way of Beartooth pass (6-10% grades for 20 miles) and have pulled it up US 14A through the Big Horn Mountains of Wyoming (8-12% grades with a few 14% spots for 17 miles). It does OK in the mountains, but you do run out of power around 10,000 ft. Both of the passes I have mentioned are not recomended for campers, but it does it pretty well. Where you will see your issue, (if it is) is you will not be the fastest one up the passes, but it will do it. You may get passed by a diesel pulling the same size camper, but they are probably not stock either.
Hope it helps.
Skattracker,
I live in Minnesota too. Do you live anywhere near St. Paul?
Also, is your 5th wheel at 9500 pounds empty or is that the weight when you are going camping and you have all you gear with you? I'm looking at a 5th wheel that weighs 9700 pounds empty so may weigh 11,000 pounds loaded. Do you think I could take that over the Big Horns?
Thanks,

figure in that you'll need a bearing kit to swap from a 3.73 to anything over 4.10 (i think) you'll need a different pinion bearing. what most people do if they don't have an abundance of shims laying around, is they will order a master install kit for both axles that will come with all new bearings, shims, seals ect. OR you can order JUST the new pinion bearing and a mini-install kit that has just the shims and seals. i actually did this on my F250 when we took the diff apart, the bearings were still in real good shape (shoulda been the truck only had about 10K miles on it).
the rear is pretty easy, you can shange out the rear with the tires still on the truck....... remove drive shaft (i did any way), slide axles about a foot out of the hub and your ready to start taking things apart. the front is alittle more detailed, since you have to take the front hub and axles out. but it is very doable.

The 9500 lbs is a scaled weight on my way back from camping up north. I also pull my boat behind mine up to Canada, so that adds another 2000 lbs.
Youe truck will pull the camper, and over the Big Horns, but you will not be the fastest. I recomend taking US 16, and not US 14, 16 is easier both up and down.
I live near Buffalo.
It's your call. Personally I would not be without it. I like to know what is going on in the engine and Trans.
Happy Travels

Stock I have pulled the smokies with a 40th 5th wheel (13,000+lbs) with a 16ft boat and did ok, Put the 5star tuner in before my last trip to Alabama and it was unbeleavalbe, hills I went into at 65 and came out of at 52 I now went into at 65 and came out of at 65, since then I installed a complete Banks system but havn't had the 5th wheel on it yet, I can't wait. I would think yours would pull 10,000 lbs easy. I have been looking into re-gearing also, found all the parts including the limited slip for about $900 on line---Ford gears, no knockoff stuff. But with as much power as I have now I don't think it will be necessary.... I can smoke the tires if I'm not careful... almost like I was young again back in the days when tri-power and Malory was the best thing going
I would also take 2 spare tires for that new trailer..... you will thank me before you get back..... also either have a good road service or your own 3 1/2 ton floor jack !!

The biggest problem in the Rockies I have learned is the altitude, not much air for the engine above 8000'. Dsl turbo's will keep ramming air into them.

What tunes did you get?
Did you notice a MPG gain when towing?
Excited to try, but have to wait.
Thanks
