3:73 or 4:10?
I am getting ready to purchase a New F350sd 4/4 diesel, I am not sure which gearing I should get. I will be driving a lot of highway miles and some towing. How much milage difference between the two?
Thanks

P.S. Because of the power of the diesel I see a lot of people ordering then Super Dutys with a 3.73 Ratio. For what you would do, you would probably be ok with that.

I've got a 2005 F350 PSD SB CC 4x4 and went with the 3.73s. In hindsight, the 4.10s would've been a better option. If you're going dually, I'd consider 4.10s a minimum, or 4.30s.

If the Single-rear-wheel came with a 4.10 I would have opted for the 4.10
I'm putting 35's on the truck today and staying with the 3.73 gears. (seems like many here have done the same with diesels) and not noticed any difference in mileage and driveability. But would have prefered 4.10

I have an '05 F350 CC DRW 6.0 with the 4.10. It tows great and gets about 17 on the highway unloaded and you can expect about 13 in city driving (depends on how heavy your right foot is). I wouldn't even consider anything less than the 4.10 for a DRW. IMO, it's the best all aroung gearing for power and decent mileage.
