none avaliable except the stock for the rear, and none at all for the front. This is if you have a SWB I6... for the LWB and V8 TB's, there are several for the rears, but none for the front.
Fill out your vehicle in the upper right corner of your posts, so we can see what you have.

Gears are available from the dealer, or any competent gear store like Randy's Ring and Pinion (http://www.ringpinion.com/). Installation is always the bitch.
No locker in the front. We share the front aluminum differential with the Hummer H3, and they're screaming for one. HOWEVER, don't think the front locker is the answer to tough trails. It will only allow you to destroy front CV shafts that much easier. If you're on a trail so tough that you need a front locker, you should be thinking about getting a strap assist or using your winch.
You *do* have a plan to install a front winch if you're thinking about such tough trails? We need to talk. :yes:
And why did you buy it without the G80 rear locker option if offroading is so important to you? Sigh - there's $1000 that you really HAVE to spend.

Yeah I just want something for the Sand. I went to the beach this week end and i just noticed at only 3 wheels where spinning. I didn't get stuck but it was fun.

Anyone know about how much it would cost me to swap my 3:42 gears with the 3:73 gears and install a G80??

If 3 wheels were spinning in the sand, and 2 of them were rears, I'd check to see that you don't already have the G80... The code is in your glove box...
Probably the cheapest thing to do fo the gears and rear locker is go to a junkyard and pull the front and rear ends out of a TB that had those from the factory.
I'd hazard to guess it'd cost you close to $2k to get the gears in front and rear, and locker in rear purchased and installed in your TB, if you just retrofit your current stuff...

Massive amount of labor to change the front gearset. I'd guess $2500 for the whole enchilada, but labor rates are high here. It would definitely be a marginal improvement to change the gears, although the G80 should be mandatory for anybody serious about 4-wheeling.

As low as $500 and dealer up to $725 - just did my G80 spiders, and the shop did a great job... all the noise is GONE... NOW (dang!) I can hear a growl from the front right wheel (and already did the axles two weeks ago, 100K on it) so not sure what that is... but the rear work done by an honest shop can be an
easy $1200+...

I don't know your location, but if you're near northern California contact these folks: http://www.rearendshop.com/
Dan can tell you what you can do with what you have or he can sell you a complete assembly.
