well i work at UPS and start at 3 in the morning, it's all city driving , but at 3:00AM so, kind of an average and i figured that city MPGs would go up, also i probably should have mentioned this sooner but this stock wheels and suspension, so this is for more of a street/strip application. and i have also been thinking maybe, 373s but 410s are $20 cheaper. thanks for all of your help so far.

What he said^^^. I'm assuming you guys that suspect a loss have never actually done it?? I GAINED 1-2 everywhere, and have seen a best of 3 mpg increase. There are ZERO downsides from doing a gear change.
3.55 to 3.73 is NOT worth the cost or the effort for such a small change in ratio. You will not regret 4.10's. It completely transformed my truck across the board.

3.73 to 4.10...worth it?
Hi
I bought a used 2005 fx4 (50K miles) with 6 inch lift and it has 325/60/18 tires. I also added Custom 87 tunes (performance, tow, MPG) from VMP but am just not happy with the pick up or mileage in the truck.
I live in Austin, tx and am mainly city driving up and down hills in NW austin so I am wondering if a gear change from 3.73LS to 4.10 would help me?
Thoughts?

I went 4.11's and I have smaller then factory diameter tires. I wish 4.30's were made for our 9.75 rear ends.

People to this day still don't beleive my truck was getting 21-22mpg before I installed my blower. Which on the highway I see anywhere from 17-19mpg. Depends on how fast I drive(70-85mph).

I think these trucks should come with 4.10's out of the factory. They are the heaviest trucks out there but still have the same gears as the light weight 97-03's. Look at the Tundra's they come with 4.30's from the factory, and they perform really well compared to a comparable F150 with 3.55/3.73 gear ratio.
