for mild wheeling you will be fine with limited slip. I had factory rear limited slip and open diff on the front of my old YJ and did fine in a lot of places you would think you would you would need more.

I have factory limited slip rear on my JK, and plan on adding Detroit Truetrac limited slip on the front also. Local shop will do it for $600. If I ever start getting into any places I have trouble I'll think about a locker then.

What type of "minor" off-roading do you plan on doing?

It sounds like you probably won't need a locker if your only doing minor/easy trails.

For the price difference of the LSD vs Locker (which requires the electronic disco's), I would go with the LSD, unless the extra $1,500 or so isn't an issue.

i would like to go through some decent mud/water, like 6+ inches perhaps. my biggest concern is, if i was to try to climb a hill and lets say the jeep tilts and one of the rear tire isnt touching that ground. will i be able to get out of it with the LSD? and i was wondering if i could get a simple explination of both and how they work. cuz all i know is the lockers lock both wheels, so no matter what they both spin when you give it gas. am i right?

Yes and no,, LSD (at least the Detroit Truetrac) when a wheel spins it transfers 3 times the torque to the other wheel. When a wheel is actually in the air there is 0 traction, so 0 torque so nothing to transfer..

On older Jeeps, if you touch the brakes a little, that causes drag and gives the LSD some torque to transfer.

The new JKs have the TSC (Traction control system) see page 101 of your manual. Which in essence works almost like a limited slip (only transfering torque a 1 to 1 ratio), and is on even when ESP is off. It will apply the brakes automatically to any wheel spinning, so you don't have to, forcing the LSD to transfer torque to the wheel on the ground.

This is not an ideal set up if you are going to off road a lot, then you should probably have a locker. But for the occasional off road excursion you should be fine.

But of course, if you can afford it, lockers are better.

It's a moot point. You talk about light wheelin'. 6 inches of water/mud today = 18 inches tomorrow. You will no doubt one day wish you had a locker. You can always go aftermarket locker after you find your Jeep. The truth is you will never be completely satisfied. You are about to open a big can of worms. You'll see

I wanted to make a reference to your age and LSD but I won't. This is technical page.

Ahhhmmmm!!! I have an 08 X with rear LSD from the factory!!!!

The LSD or the Electronic locker on the rear are options on the X

On the 2 door they are only available on the X if it has the S package, which is $2900. This brings the MSRP to 23,900 for X 2 door with rear locker or 23,400 with rear LSD and 3.73 rear.

You can get a base 4 door with tow package (to get the 3.73 gears, only because dealers never order the gears without the tow package) and LSD for 23,800 (that is what I got) Jumps to 25,400 for the rear locker, as it seems they only put rear locker on 4 door hardtops.

wow instead of getting the S package I would just go as basic as possible and buy the mopar rubicon D44 axles that come with lockers already assembled. I just bought my set for $3k and they have the 4.10 gears already.
