i had recently installed 4:56's in my 06 4x4 screw which had 3:55's i now run 37'' tires and have not seen any decrease in my mpgs on the hwy i see about 15-16mpg and about 14-15mpg city. like everyone has said on here its all in how you drive!!! also i leave my edge on stage 2 (stock tune) all time if this helps, dont forget to reprogram you gear and tire ratio. hope this helps

Found a set of 4.30's for 9.75's.
Ford Racing makes a set of 4.30's for the 8.8.

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.

also when you go from 3.08 to 3.55 your 1st gear launch will spin tired more easily.
my 08 is heavier and less aerodynamic than my 04 was so that is mostly why the MPGs went down. but if you were changing the gearing in your truck(not trading in like i did... long story)then you will be making it quicker unless you have to shift more like i do now.

4.30 Gears...Anyone using these?
Never mind...I see these are for rear application only....not 4x4
Hi,
Thanks for the link...is anyone using these in a 2004 - 2008 4X4?
Thoughts?
