I'm wanting to get a 6 inch lift and 35's. I have stock 3.55 limited slip gears now, and I know they aren't strong enough. I have a 2006 F-150 4X4 with the 5.4 V8. This truck is my daily driver. I'm thinking 4.56 gears. I do a good bit of highway driving so 4.88's might be too low for me. I don't plan to go up to 37's. Who has 35's and can tell me your milage with whatever gears you have? And what are the best gears? A lot of people are saying Yukons

 

Somebody has to have some numbers

 

I seem to be at around 15 to 16 with my tires and stock 3:73 gear ratio,,but i am planning to re-gear in the near future just have to decide on either 4:10's or 4:30's yet..

 

I have 4.88's with 35's and pull 15 not pulling anything and taking it easy. Pulling a 4000lbs I get 8 to 10.

 

So I would probably get 1 or 2 mpg better with 4.56s than you do with 4.88s when I'm not towing anything?

 

Yes, you probably are correct. If you baby the truck completely, but who does that? I would rather be over geared a little than under, but just my thoughts.

 

35s and 4.56s nets me about 15-16 average and i tend to heavy foot it quite a bit
thats about 40/60 city highway. i can consistently see 16 in the city without too much stop and go

 

Is there a gear ratio between 4.10 and 4.56?

 

4.30...but they dont make a reverse rotation for it so you can only get the 4.30 if ur 2wd

 

Too bad. That sounds like it would work good for me
