If your'e going to change gearing go to something like 4.56 , 4.10 is not enough. You can get gears from someplace like bronco graveyard and then have someone install. Should be able to do it for around 400.00, makes a big difference.

Find a tire size/gear ratio calcualtor.
It should give engine rpm's at a given speed based on your 35's and 4.56's.
I would think the 4.56's would keep you within specs for motor rpm's with the 35's.

try this calculator, use the one on the left side, E4OD for tranny, BW 1356 for transfer case, 4.56 for gear ratio, and 35" tires, at 25oo rpm you'd be doing 80mph.
You can play with the numbers too:

i think 4.10 will be fine.. he does allot of highway driving.. so 4.10 will be best.. i have 4.10 and im upgrading to 35"s soon and i wont change the gears
at 80 you will be hitting 2445 RPM so its no big difference between the 4.56's

4:10's should be fine. I had 3:55's and was running 36" tires and could still squeel them off the line. Now I'm running 4:56 gears but that's because I want to run a bigger tire. I wish I had 4:10's instead for highway and you can always use 4Lo when you need it offroad. What engine do you have? That will also determine how doggy/not it is while driving.

alright there is something fishy about that calculator...
I checked it with
e4od
bw1356
4.10 gears
35" tires
it said in 4th gear at 5k rpm the vehicle would be going 179 mph?????? WTF?

try the 35's with what you have.
if you were closer to N.J., i would gladly swap the 4.10 rears i have in my 88 for your 3.55's.
i have 36's on the 88, and am always looking for another gear.
