What gear ratio do I want?

I drive a 87 yj, 6cyl, auto trans and love it. It has dana30/35 axles, with the 35 lincoln locked. I do most of my driving on the road (altho its not my DD), and really don't like the rear locked. So.... Its time for a new setup, and I'm thinking 8.8. The question is : I currently have 3.54 : 1 gears and really don't have a problem with them. I seem to have plenty of power and I can go up and down the road with very little downshifting. I can get the 8.8 with these gears and not have to do anything with my front axle. I currently run 33" tires and don't plan on going any bigger, and will probably put a lunchbox locker in the front and maybe a detroit locker in the rear. I use my jeep mainly for hunting so it sees mud and snow, very few rocks. Do you guys think the 3.54s will be alright for me or should I go to 4.11s. Your thoughts?

There is also 3.73 which is as common or more common than the 4.10. I would pick a ratio and stick the Detroit up front when you regear because you'll need a new carrier with the switch. What are your plans with your jeep? Are you going to go bigger with tires? I'd maybe go 4.10 and leave an option to put bigger shoes on.

3.73 limited slip 8.8 rear axles are very common. I bought one for $250 last week. Limited slip is great on the street and helps in snow and mud. You could come across matching gears up front with little trouble.

I love my Detroit OP, if you have to regear it's a great locker even in the rear. I never really notice mine while driving and it does amazing off road.
