ARB used to be a popular air-locker.

Looks like they're still around.

It is a diff lock like most tractors have. Instead of pushing on the lever with your foot you push a button or turn on a switch.

I have had them on a few trucks now and will simply not buy another without a true locker. There is no comparison.

Is this the same as what happens when you put the truck in 4WD? Or is that only locking the center diff?

No, not the same thing. 4 wheel drive is actually kind of a myth. Remember the movie My Cousin Vinny? Remember how the car only spun one rear wheel?

In most vehicle only one wheel spins on each axle. This is the "normal" setup. A vehicle with a limited slip differential or as some call it, posi-traction, can lock up both wheels to a point but use clutch packs that will release and engage depending on the situation.

A e-locker actually mechanically locks the axle solid. Both wheels have to spin at the same rate. Because of this you get maximum traction but only works well in a straight line. There is an independent switch that engages a locker seperate and is an independent system from the 4x4 switch and system.

In the case of my Nissan Titan the switch is on the dash. In the case of my F150 it's actually part of the 4x4 switch. You rotate the switch to do normal 4x4 operation and pull it out to engage the e-locker.

I believe at this time Ford, Nissan, and Toyota are the only ones offering it. Nissan has had it on the trucks for about 10 years, Toyota followed, then Ford around 2008.

I drove a base model 2013 F150 4x4 at work with locker. You actually pull the knob out to engage. I believe that the front 2 are locked any time it's in 4wd? You can also just pull the knob to lock rears in 2wd, but don't do it in motion. You will be surprised the difference it makes;

Generally, you don't put a locker up front for an onroad vehicle because it can cause problems with going around corners, so I would be very surprised if Ford did that.

jeep offers lockers and so does dodge (on certain models)

You are correct. Ford does not offer a locker for the front axle. I don't think anybody does from the factory. Those are strictly aftermarket and for off-road use only.

I think Ford's e-locker rearend automatically unlocks at 25 MPH. Is that right Diamondpilot?

 

[paulharvey]

This one didn't unlock at speed. You could forget it on if you where straight line driving. I had assumed the fronts both pulled in 4; but we know what ***-u-me does...
