I have a 2006 XLT 4x4. 35" tires, roof basket with spare tire, lots of mods.
I do some pretty light - medium towing like my 17" fishing boat, tent trailer, waterfowl trailer. And I do lots of highway/100lm/h+ driving.
Which gears should I get? 4.10, 4.56, 4.88. I've heard with 4.56 I will be getting the worst mileage.
ANy suggestions?
Thanks

 

I would say either 4.10 or 4.56. I would lean to the 4.10 as you dont sound like you do much towing. If you have lots of hills or plan on getting heavier things to tow, I would go with the 4.56s.

 

I live in Alberta Canada, so lots of hills and mountains.

 

Any other opinions?

 

4.30 best of both worlds

 

. There is no such this for our f150s 4.10 or 4.56

 

Go 4.56 and not regret not having enough.

 

You are correct I'm thinking of my 8.8 in my 5.0. I'm going 4.56 myself as a result of no 430s available for the 9.75 reared. I just don't think the 4.10 will make that much of a difference.
