Rear or front lockers?

I'm new to off-roading and was curious what front and rear lockers do and how important it is to get them

A locker will make the wheel on the left turn at the same speed as the wheel on the right nomatter what. The best way to understand it is to A. go wheel some yourself (with others) and B. search on youtube for -ARB Locker Benefits.

Now ARB is a brand of locker. Many different brands of lockers out there.

Lets say you are wanting to get up a hill and the hill has ruts from other jeeps. You put the jeep into 4wd but as you make your way up the hill the front left tire spins and the front right tire is not moving at all. It is because the diff sent all the power to the left wheel. The LOCKER will make the two wheel move together. It LOCKS the axles of each wheel together.

Now you go up the same hill in 4wd again but this time you lock the fron axle. when you get to the same spot that u got stuck before both wheels will turn rather then only the left. The addition of the right wheel spinning will pull you up and over the hill.

You can take you jeep almost everywhere without lockers it just takes more of the skinny pedal and is really hard on the jeep. Once you get into advance stuff lockers are needed.

Many people never add a locker but once you do you will never want to get rid of them.

Automatic posi lockers are great for the front. They work great in 4wd and are almost not noticeable in 2wd when on the road. This is gonna be your cheapest option.
If you choose to lock the rear then you're gonna want something that you can dis-engage or the limited slip diff. Both are more expensive.

Welcome to the site & welcome to the world of off-road. You'll have a blast.

Here's a perfect example of lockers vs. open diffs.

Lock the front. Search Aussie locker.
Swap your rear end with a limited slip diff out of an explorer (8.8)

If you drive the jeep on road daily, you will hate having the rear locked.

I've been driving jeeps with rear lockers for about a decade They drive fine. On road sometimes on tight corners the tire will chip a little
