Gears & Locker - What shall I do?

I want to take the gear, lift & locker plunge.I've
got a date to meet several friends in Colorado for 3 weeks
at the end of July and August. They carried me last year.

I have a '92 YJ, 2.5, 2" bodylift, 31x10.50 GY MTR's,
and would like to go with 4.88 gears, simple 1 1/2
Superlift, and a locker in the rear.

I finally found a good mechanic, but would like some
input from those of you who have changed gears and
have some experience with the various lockers.

The limited slip locker has been recommended
because of the Dana 35 axle. Some lockers seem
to easier to install than others.

In the 4WDrive & Rosser Magazines I see the different
lockers advertized. There is the standard Trac-Lock,
Detroit gearless and E-Z lockers, then the Lock-Right,
& Power-trac, then I saw a Detroit True-trac...

What's your experience? and where to order?
And what installaton kits or parts need to be included?
I have hears it's pretty standard to change bearings
and things when upgrading.

Having to do with gears....

- Is there a real difference going from 410 to 456?

- I want to tow a little camper and the 2.5 needs
some extra power, so the 4.88's idea came up.

- To save a little money, my mechanic will install
what I buy, so where's the best deal for gears
and some of the other parts I will need?

* Plans for a simple 1 1/2 Superlift, clearance is good,
but the old springs are really flat. Already have
some Rancho shocks.

When it comes to some simple power tips for the
2.5, what really makes a difference, yet within
a budget?

Lastly, are there any problems in ordering parts from
Rosser, 4wDrive, JC Whitney, and others? Some
of the mechanics I have talked to take a
percentage on parts, and the prices really vary.
But is there a real quality problem when ordering
from these magazines?

As you can see, it's been a while, since I was
on the forum last....Hope to get some help.

you know that all sounds like a good plan, but you really want a little larger lift for rock clearance, and little larger tires, i know that is probably to late of notice for all this, my friend has a cherokee with 30"tires stock lift..he kept the weak rear end and put lockers in the rear ox locker up front, and put the super 35 kit on the rear and he does really really well..lockers make a huge difference i mean if you are just going to be a road queen most of the time just shoot for lockers thats a good upgrade then again my friends xj is a 6cyl if you planning on offroading you will want a little stronger rearend d44 more power a 6cyl and a sye after a large lift..others may disagree with me but that is what i would do..what ever makes you happy though man enjoy the jeep for what its worth

A limited slip is not enough of an improvement to make your investment pay off. Don't bother, might as well be open. Don't bother putting an EZ locker or any other kind of drop in, lunchbox, or whatever you want to call it in the rear. It won't hold up! It won't!

If you're going to put a locker in the rear your worthwhile choices are very limited. ARB, Detroit or Ox. I wouldn't waste my money on anything else.

If you're already running 4.10s, then no, the 4.56s are not enough of a change to make the significant investment worth your while either. Just stick with the 4.10s till you're ready for 4.88s. From 4.10 to 4.56 you're not getting even a 1/2 turn added. No chance is that worth it considering you're talking about $500 per axle installed.
