RE: Do all rams have the anti slip diff?
No all rams do not have anti slip. And it is the same as a posi just a differnt company. What is does is engages when one wheel begins to loose power. With 4x4s it isnt good because it sends all the power in the front to the wheel with the least traction, so in mud you just sink down to one side. The anti-slip allows you to turn on dry roads as well because the tires can spin at different speeds, but keep you moving on wet roads because it will grab.

RE: Do all rams have the anti slip diff?
When I ordered my 2007 Ram 2500, the anti-slip rear diff was a $300 option. The word "posi" is an abbreviated form of the Chevrolet trademark "Positraction" that they developed in the 1950s. It's just the name that Chevy gave to a clutch-type limited slip diff.
When sharx ram says you can get them with lockers, he means you can install aftermarket locking mechanisms (Detriot Locker, ARB Air Locker, etc) to your front and rear differentials. Lockers have never been available as factory options.
Wikipedia has good articles on the topics of limited slip and locking differentials, if you want to learn more about them.

so with antislip you will sink in mud to one side or without it you will? antislip makes the trucks a lil hard to corner as well compared to non posi?right

The anti-slip diff has clutches to help turn the other shaft, but allow slippage to help with cornering. They can only transmit a max of 80% of the torque from the slipping side to the side with better traction. If you abuse them by a lot of heavy off-roading, mudding, etc, you can burn up the clutches.
The lockers are more beefy, and tend to engage with a clunk when one side starts to slip. Years ago I read about a locker called the Powertrax No-Slip Differential, which is supposed to be smooth like an anti-slip without using clutches. I don't know anybody who uses a Powertrax, but it sounds really good.

i do believe that the third gen rams with the AAM axles use a gear driven anti-spin with no clutch packs to wear out.

this is why 3rd gen axels do not require friction modifyer.
sometimes they work. . .sometimes they dont, mine has always worked when one wheel begins the peg leg. some have stated that you need to apply the brakes a bit to bring up a load onto the axel to get the worm gears to engage.

Axles with open diffs (no anti-slip or locker) will always corner better, although the ARB Air Locker should corner just fine when it's not engaged.

They can only transmit a max of 80% of the torque from the slipping side to the side with better traction. If you abuse them by a lot of heavy off-roading, mudding, etc, you can burn up the clutches.

I love mine because it's a true locker when I need it most. It won't slip like an LSD or anti-slip rear when I'm in the sticky stuff,yet it still lets me go around corners if i back off.
But this isn't for everyone....many guys can't stand it because it causes under-steer around a fast corner if you stay on the gas. Here's the page for everyone: http://www.powertrax.com/
