4.10s with stock YJ 4.0

This question is probably the opposite of what everybody usually asks on here. At least thats what is seems after searching through Jeep forums for the last hour or so.

Anyway, Ive got a stock 95 YJ Sahara 5 speed. I have 30" BFG all terrains on it with 16" Jeep Liberty wheels. It currently has 3.07 gears. Would swapping to 4.10 axles from a 4cyl YJ be to low of a ratio? The Jeep is not my daily driver. Mostly for riding trails up by the cabin. I have a built XJ I use for the hard off road stuff. There is the potential that when the 30s wear out I would go with a 2.5" lift and 31"s. At that point 4.10s probably wouldent be so bad. But that is the future.

Only reason I ask is cause 4.10 axles happen to be available.

Thoughts?

Thanks.

Edit: I should add that 5th gear is all but unusable with the 30s. It will go ok around 55 but whenever the simplest amount of effort is needed I almost always have to downshift to 4th.

I had a 94 with the same setup your thinking about- I6, 30" tires and 4.10 from 4cyl jeep- in my opinion the gearing was too low for that small of tires. I often just started out in second gear. The gearing being off was especially noticeable on the street. My new jeep has 3.73 gears with the I6 and its much better to drive. I'd say wait on the gearing sway till you get the larger tires.

Agreed.
4.10 will be just fine and you'll have plenty of power to get going. It may not be the most fuel efficient thing on the road but show me a Jeep that is.

I do burnouts with my 32's and 4.11 gearing. It would be a bit low...

You will be fine with 4.10 gears and 30" tires.
and when they wear out you will get to move up to 31 -33" tires

You're going to have tons of power, but your RPMs are going to be way high going down the highway. Think of it this way. 225/75's fit with 3.07s. 3.54 for 31's and 4.10's give you stock power/fuel efficiency for 33's (well at least as close as possible running that size tire).
