Hey fellas, I am looking to get some input from you all. I am wanting to swap out my gears in the diffs. Currently I have 3.55, NP435 tranny, and NP205 TC. I am trying to decide between 4.10 and 4.56. I am running 33x14.5 STS's now. I am not sure if i will change to 35's the next time I need tires or stay with 33's. I have looked at gear ratio/rpm charts, but I would like to get some input from guys that have similar set ups. I drive my jeep on both road and off.
