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.
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.
