I used to know this but very unsure, I have 3.06's in front and 3.07's in back is this cool with a NP205?

3.06 and 3.07 is basically the same thing, I had 4.10/ 4.11,with a 205, ran fine. Its only 1 hundreth of a rotation off, In 4wheel drive ,especially in dirt ,sand or snow, your 205 wont know the difference. I wouldnt mismatch gears any higher,or lower, and drive on pavement,you will just be asking for Tranny problems later.:beer:

You will be fine with that gear combo.. Ford used 3.50 in the rear 9 inch with 3.54 in the front D44 fron the factory which is the widest spread I have seen.. By the way tire pressure mismatch will have more of an effeft then the slight ratio mismatch..

Sweet thanks guy's

Isnt the rule they can be within 1% of each other, so 4.11s would be .04. If you had 4.09 front, you would be within the limit.

You can go 1% difference for any on road driving or 2% for offroad. That what Randy's R&P told me.

I know this isn't the Toy section, but some of the Yota guys are running 5.29's in the front, with 5.38's in the back with no problems :D

It's the other way around. 5.29 (Toy) in the rear, 5.38 (D44) in front. Very common setup with the SAS guys.

Just curious, where did you get the axles?

Sometimes gears are commonly reffered to by a number slightly different then their actual ratio, so if you had a chance, it would be good to count teeth.

For example, some people say that they have 4.11's in their Chevy, when there are really 41 ring gear teeth and 10 pinion teeth, which is exactly 4.10.

the reason I have been told from reider racing anyway, is that the diffrent manufactures of gears had patent s and shit on em, that is why you here 4.11/4.10s stuff like that cause they are that % off to avoid patent conflicts just thought Id throw that out there, that is what they told me when I asked :skull:

the patents deal is a new one on me, maybe I've just never heard of it before. But as to the gear mismatch, like E1 says, generally 1% is acceptable. Your turning radius will offset the gear offset, thus equaling the overall rotational factors. (if that makes any sense).
