I have 35" BFG Muds and may go to 37", I would like to know what the correct gear ratio would be for optimal power and fuel ecc. I have a rancho and I am getting a edge programmer. Also where is the best place to get these gears??

Thanks for all the help

 

I would say 4.56s, I have 37's and I'm putting on 4.56s on Friday, if you want to wait I will let you know how it feels.

 

4.11s if it's mostly highway. 4.56s if you do any towing or serious off roading.

 

IMHO i would go with 4.88's. Just to compensate for the added weight of the tires as well as the height.

 

with 37" i would recomend 4.88 it would get you the closest to your stock overall drive ratio, good luck

 

my suggestion would be 4:56's because they would do ok with a 37" tire but if for some reason you decided to downgrade in the future I think 4:88's with 35's might be to low. Just my .02

 

4.88

 

4.88

 

I have 35" tires also. How much should I expect to pay for new gears?

 

At least $500 per axle.
