Shop wanted $2300 to regear. Needless to say I will be doing an axle swap myself. Not paying anyone to do it.

Don't forget the 3/4 and one ton are 8 lug so you'll need wheels too

$2300 to install new gears is retarded. Call around and get more quotes.

called another 4x4 shop. They quoted me $900 to regear to 3.73

Still going for the 35's? If paying to regear I'd go straight to 4.10's. You won't be sorry.

I have 33s and 4.56. I used to have 3.55s. It's night and day. I think 4.56 are just right for 33s

You can do the math to decide. Measuring around the tread what % more inches is the new tire compared to the stock one.(or calculate - remember pi R squared ?)
You need your driveshaft to turn that % more times to make your wheel go around once in order to stay in the torque range.
3:55 gears mean the driveshaft will turn 3.55 times for the wheel to go around once.
If your tire is 20% bigger around than the old ones then your gears need to be 20% lower (higher number) or the closest equivalent you can find.
3.55 x 1.2 = 4.26 which in that example 4:10 would be pretty close
What you want is for the motor to go around the same number of times to move the truck 10 feet down the road

I just finished the last math course I'll ever have to take last semester. Give me a couple years of rest and I'll attempt this lmfao

yokes are different, lug pattern is different, 250/350 axles have perches for 3" wide leafs, since your truck is 2wd it only has 2.5" wide leafs. i dont think that matters but im unsure.

axle width is the same.

i just got a 10.25 for my 250 actually (going from 3.55 open to 4.10l)

also the axle code your looking for is C5. that's the f250-350 axle code, and honestly that's what id get a axle out of.
