What to do, what to do...?

In a bit of a dilemma here so here's my two choices...not gonna set up a poll cuz I'm open to other opinions as well.

My eventual goal with my Jeep is to put Detroit Truetracs front and rear...lift it and put 33's on it...as well as re-gear it at a later date to keep the use of 5th gear.

I decided over the winter, instead of lifting it...I want to work on getting the Truetracs so I have traction. My problem however is the rear truetrac for my current gearing 3.73 will not work when I change my gears...it's designed for UP TO 3.73 gears. The front is designed for 3.73+ so it'll work regardless.

What I'm thinking is... hold off on doing the rear end and leaving it open and then putting the front truetrac in. I realize I will only see the advantages of limited slip while in 4wd, but will I see better results with limited slip in the back or the front?

The other choice is to go ahead and do both...and stick with a 32" tire or 33" tire without changing the gear (effectively losing 5th gear in a lot of situations).

Or....something else I thought of...if I changed my gearing to 4.10's (would that be best for 33" tires with an 02 5 spd and 4.0?) or whatever is best for the previously mentioned setup, would it kill my performance and gas mileage before I get the tire size bumped up? Obviously my RPMs would increase...but would it be an astronomical increase?

Thoughts? How would you do this if you were in my shoes...

If I had the cash...roughly $4000...I'd just do EVERYTHING all at once, but I'm not rich. lol

I would re gear it if your doing bigger tires because it will help with power and gas mileage. I have a dana 30 in the front and 35 in the back. I re geared to 456 and added 35'' tires and i get near factory driving with good power and better gas millage. I got my gears and gear housings through rusty's. I don't have lockers cuz you really don't need em. I spent under a grand for the parts and the install.

Would regearing 9 months before I get the tires cause issues though? I won't be able to afford the tires until next summer at the earliest...but they're definitely gonna be done eventually.

The Truetracs aren't lockers...they're gear-based limited slip differentials. Being in Ohio, I see a lot of snow and ice driving (like you probably do over in PA I'm sure...lol) so I don't want to jeopardize snow/ice driving performance for traction...but right now both my differentials are open diffs and my Jeep sucks in the snow. Just can't seem to keep traction once the snow starts to get deep and living/working out in the country...the snow gets pretty deep. lol

And now as I sit surfing craigslist...I'm beginning to think...why not just leave my Jeep fairly close to stock, maybe do a BB and 32's...and buy a Yamaha Grizzly with a trailer. Then I can trailer it places, beat the hell out of it, and not worry about killing my DD. Chances are, my Jeep will rarely leave the road anyway...I love using it for winter driving and little things around work, but it doesn't need to be super done up for that stuff. Maybe just the differentials, new tires, slight lift... argh. I hate being indecisive. lol
