33s on 4.56 would be awesome wheelin though!

anyways, theres a few people on here who ran 3.55 and 32s or bigger with the 4.0 .... most of those guys have 4.10 ls or are planning on it very soon

I ran 3.73 gears and 33's on my 98 4.0L 4x4 with 5 speed, I didn't like it much.
If the truck is strictly driven on the road and you don't tow or haul much, it won't be that bad. Driving up bigger hills, I had to downshift to 3rd with my manual trans.
Anything offroad that actually requires 4x4 will require 4x4 low (deep snow, mud, sand, etc). Trying to get a trailer moving from a stop is miserable. The auto will do it but it will heat up a lot. If you do it, definitely get a bigger trans cooler.
4.10's would be alright, 4.56 would probably work pretty well. I ran 4.88's on 33's with the sport trac (4.0L sohc automatic) and I loved that setup when I lived in Oregon (lower speed limits). The OHV doesn't like to rev as high as the SOHC, which makes me think the 4.56 would be tolerable and more ideal IF you have the truck offroad and/or tow. Especially if the truck isn't your daily driver. Re-gearing is going to cost a lot, and I wouldn't spend that kind of money JUST to get 4.10 gears. Just my opinion.

I have 4.56's with 33's and love it!

I have 4.56's for sale....

how much ??

FWIW, and as a point for comparison, the FX4 came stock with 31's and a 4.10 gear, so a 4.56 with 33's would be just about back to stock gearing.

um...this threads like a year old lol he probably sold them already. pm him or something

Yeah, but we love re-hashing old topics!

i have 31 on my 3.0 with 3.73s and i would strongly advise going to at least a 4.10 gear runnin 33s.....im goin with 4.56 gears when i get my 33s but i do alot of offroading
