gears for 37s?
i have an 06 f150 xlt with 35" tires and about a 7.5 lift all around front and rear after adjustables were installed.. i know 100% 37s will fit in their well, and im planning on getting a set in 3 or 4 weeks. I have a programmer and all that good stuff intake exhaust truck has everything set for the bigger tires, even upgraded brakes. the only thing it doesnt have is gearing, now everyone says once you get 37s gearing is basically a must. i dont know much about the gearing, but i wana decide on a set. I DO ALOT OF CITY DRIVING, stop and go stop and go, but i also do a ton of highways driving shore in the summer poconoes ion the winter, what gears would fit nice? i am not hard oin the gas anymore trying to save mpgs but i do want the 37s.. should i get 4.11 4.56 4.88s ? i like the ford racing products any other opinions? please chime in i am going to have to buy these soon guys.. thanks!

4.88's, biggest gears you can fit in the front diff. 4.56's and 4.88's are quite similar, go with 4.88's IMO
4.88 gears, 37's, 4.88's= around 1860 rpm @ 60 mph
4.56 gears, 37's, 4.56's= around 1740 rpm @ 60 mph
4.88 gears, 37's, 4.88's= around 1860 rpm @ 60 mph
4.56 gears, 37's, 4.56's= around 1740 rpm @ 60 mph

4.88's would get you off the line faster, 4.56's would be better on the highway, however the difference would be so slight it would barely matter, like you probably wouldn't even notice
