Gear ratio?

Hi,
I put a 3 inch body lift on my Big Bronco. I just got a 6 inch suspension lift and will install this weekend. I have 35s right now (YES 35s under a 3inch body lift NO CUTTING FENDERS OR OTHER MODIFICATIONS). DOES ANYBODY KNOW WHAT I SHOULD CHANGE THE GEARS TO? I got my printout from Ford so, I know what I have now - 3.55 rear axle ration- And I know my gear ratios now. When I go to buy new gear what size should it be?
Thanks in advance.

I'm not positive on this, but when I was researching the same question I came up with 4.56. Supposedly this would keep the drivetrain running the same as if it were stock again. Help me out guys, I might be wrong on this one! I don't have the formulas for this.

I would go with at least a 4.56 gear ratio, or maybe even 4.88s It really has to do with the way you use the vehicle, and the mods you have done to it.

You should be very happy with the overall performance of 4.56s and 35" tires. If you do some nasty offroading quite frequently, maybe even 4.88.

Thanks guys...

Now, WHAT SIZE DO I NEED? I SEE THERE ARE 8.8, 9. MY BRONCO IS 1990 EDDIE BAUER EDDITION. IT IS 4X4 WITH AN E4OD TRANNY. SO, HOW DO I FIND OUT WHICH TO GET?
