I am going to regear and am trying to decide between 4.56 and 4.10.
I have an Auto with 31's now but will be getting 32s this summer, actually 265/75-16s which are between 32/11.50s and 33/12.50s . I am only going to regear once and would like to pick up some power. I drive the vehicle 2-3 hrs to wheel sometimes and take one or two 5+ hour trips a year do you think 4.56's would be too much on the h-way.
I am leaning to the 4.56's for the better offroad ability, and from whay Ive been told the new cam in my engine has shifted the power band up 300-400rpm. The 4.10s would put the rpms about 5% higher(~100rpm) than my stock gear/tire combo-3.55's. I figured that the engine would be turning 2300rpms at 65mph with the 4.56 and 32s with OD. Is this true in the real world? I turn 2000 at 70 with 235s.
If 4.30s were avail for the front Id get them but the jump is to 4.56 so...

Sorry to ramble, Im just looking for some opinions.

Thanks

I have a 2wd and just regeared to 4.10's. I do alot of freeway driving and have the 265/75/16. If you drive alot i wouldnt go with the 4.56. Way to much gear. Right now i'm taching about 3000 grand at 75. This sucks for the mileage. I'm over with the old people(hopefully not offending anyone)hehe :p on the freeway. When i get new tires i'm going to go with 285/75/16's. With 4.10's and 265/75/16 you real ratio is about a 3.73. It has nice pickup, but on the top end you lose. On the other hand i can have a full load, pull a trailer and still go up the mtn at 70 no prob.(slight exageration) but close.
Really its up to you...Depends on the tire size you want to go with. If you go with 33's i would lean towards the 4.56. Just depends on how much you go out and how much freeway driving you do.

Up until last week I was running 32s with 4.56, but I just sized up to 315/70s... Anyway I half agree with what Brian says. I have a heavy foot too, and regearing to 4.56 does limit your top speed more, although to be honest before, when I was running 32s with 3.73, I didn't have the power to go anywhere.

Now that I have regeared I can go quite a bit faster. By the way my RPMs are running I figure my comfortable fast speed will be about 80-85. any faster than that and I'll be sucking up to much gas. Regrearing gives you better city mileage, and you can actually go up the mountain.

Also, you'll want to look at price. 4.56 gearing is a nice round number, most people don't really ever go lower than that for their Explorer, yet it is low enough that you'll be able to run 35s if you want to in the future. Not that you are planning on it, but when you are dropping $1300 into something, its best to plan it out.
