Not to be rude, but if you dont know what they are, you will probably never miss them or need them.

To know what a locker does you first need to know what the differential does. This video will get you started. Feel free to ask any questions you have. There are plenty of folks here who'll be happy to teach you.

They helped getting up this hill - especially where you see all of the tire marks (with lockers you just crawl up the first hill, without thereís some tire spin required):

They let you do this also. Without lockers this is un-passable. I had fun with this one.

In my area, a hill like this would usually be covered with sharp, jagged rocks. Lockers help reduce sliced tires and flats by getting power to the ground on all 4 wheels thus reducing spin.

Also, going down a straight, steep hill will be easier and more controllable with lockers if your using engine braking.,as it allows all 4 tires for traction.

Some here will say you don't need them but they have their place and are yet another tool in your arsenal that you may have to pull out one day.

There are three types of differentials - open, limited slip, and locking.

Open differentials drive one wheel on the axle

Limited slip can drive either wheel on the axle; one one loses traction power will go to the other wheel

A locking differential ensures both wheels turn at the same rate as the differential carrier. You can have automatic or selectable lockers. With selectable lockers, the differential can be operated as either open or locked.

A locked differential gives maximum traction, but unless you play really hard off road you don't need it

I just had ARBs installed in both of my axles.

Yeah, it's a fun hill! Daggo - good eye, yeah some drive up to the first hill and try it but canít make it up without lockers (some do make it without lockers), or get out and look up then turn around. I must admit, the first time I saw it a few years ago I didnít even try - mainly because I was still stock and didnít have the confidence and was worried about the rocks up top which are hard to see in the pic. This last year we ran the trail again, but had to do it this time.

The control is nice. There are some rocks near the top, but they have been worn down a bit from tire spin...

While we're talking basic locker-tech, can someone opine on whether a selectable locker can be installed on a limited slip differential?

It has the feel of something where the technologies might work against each other, but it would certainly be a nice set up.

So you were born with the knowledge of what a locking differential is and what it does, therefore you have use for them, but someone who doesn't currently know what one is will never have use for one?

For the ARB, the way it is set up, you would not need a limited slip. Install the ARB (basically a locked spool when engaged), in each end of your rig and use as needed. It is truly the ultimate. This is my 15th year with them and they are virtually awesome in every way in VEX.

Best,

A selectable locker (ie ARB) replaces the carrier, so the LSD would go away. Selectable lockers are either OPEN or LOCKED... nothing in between.

No doubt lockers have their place and are the best for what they're for, but what I'm thinking of is having the limited slip for heavy snow falls while the lockers would be an off road only type of item.

For example, even in bad weather I wouldn't want to lock my axles at the outset of a 45 minute drive home from work where sometimes I might have full traction but other times may not. I'd think a limited slip would be better for those purposes.

Of course, at the moment I have neither, so it's all just thinking about the future at this point.

Thanks, that's what I suspected. Still makes me a little sad. :,(

We do have a "computerized" limited slip with the BLD, which gives you limited slip like capability.

From the Owners Manual:
TCS (Traction Control System)
This system monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, brake pressure is applied to the slipping wheel(s) to provide enhanced acceleration and stability. A feature of the TCS system functions similar to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that is not spinning. This feature remains active even if TCS and ESP are in either the “Partial Off” or “Full Off” modes. Refer to “ESP (Electronic Stability Program)” in this section.

Holy cow, I had no idea. I'm not too crazy about the Jeep tweaking my brakes while I'm driving (especially in bad weather), but even still, that's pretty cool.

Yeah, it can actually work rather well and maybe so well in fact that you haven't noticed it working for you. You can usually feel it kick in when one of your tires starts to slip.

Seriously, if you want to learn about lockers, the best way is to find someone with a jeep, and go riding with them. Have them do somethig challenging unlocked, then do it again locked. You will see a difference.

I found this video. You can see when the camera guy moves to the passenger side that the tracks show both tires were spinning, and when he tries again the driver side tire is spinning the whole time and the passenger side starts out slow but spins right along with the drivers side.

Thats not the point I was trying to get across, man you guys need some backbone.

The point I was trying to get at is that there are tons of people that come on here and get advice from people that pretend to be experts then find they didnt need it, or it wasnt right. Lockers arent cheap, they can destroy your ride if not used properly, and 80% of the time, not needed offroad. A good set of aired down tires, proper gearing, and an aware driver is much more successful than someone who is new offroad in a 37 thousand dollar toy who doesnt know how to utilize 10 thousand dollars worth of equipment on it.

On that note, there are literally thousands of online references about the benefits and negatives of lockers, how they work, and how they should be used in each application. Last time I checked, the information on wikipedia is fairly accurate and would be a good starting point. Like i said earlier though, the best way to learn about locking out, is to go jeeping with someone who is experienced with them.
