I think most of the comments here are geared towards the 2015+ with the G80's.

Someone has already posted this, but it looks like it needs saying again. 'Positraction' was simply GM's trademarked version of limited slip, which came on more cars than trucks. They came out with it in the late '50(IIRC).
Most people 'add' lockers to 4wd vehicles, as limited slip just doesn't cut it in situations where you NEED both wheels engaged(climbing over rocks, or mud-bogging for example), and usually when/if a[4wd] truck comes with an LSD, it's only in the rear. Lockers are usually activated by either air or electronically, although there are some(cheaper) ones that activate 'automatically', which is what we unfortunately get on the [newer] Z71s. One thing I liked about my F150 is that it at least came with an electric one, just like on my Jeep(which came stock with front and rear). Some people like the automatic lockers-the aftermarket kind generally speaking- but those are pretty-much for dedicated off-road vehicles, and they're noisy. Heck, some people weld 'em, but I think those might be limited to drag cars, mud-boggers, and maybe hard-core buggies

Here is a youtube video of the Eaton G80

The G80 has a more reliable action of providing traction to both wheels at slow speed...I'm old enough to remember GM Posi's not locking up on very slippery occasions(mud and wet snow) and having to trick it with ebrakes or jamming something against a spinning wheel to get the clutches in the rear end to bite.

....and I'm not saying the G80 is stronger than a old posi carrier just better for most driving conditions

a G-80 along with 4 WD gives you some serious traction. had a Quaife Torque Biasing Unit installed in my lame FWD VW jetta 1.8T when going straight both front wheels pulled, great traction + eliminating torque steer totally, a real flaw if your FWD has any real power!! when shopping for a leftover in 08 i was going to get just the posi but could not fin any being year end, found ny 12,000 mile 4WD with standard cab i wanted, a bargain @ $14,000 no trade. todays pickup prices are NUTS!!!
