Yukon duragrip. The savior of LSD?

So my friend is going back and forth between a locker and lsd/posi traction. After explaining to him the weaknesses of lsd as far as lifting a tire off the ground, he told me that someone recomended the yukon duragrip to him because it somehow does what all lsd units failed to do, which is redirect power to the wheel in contact with the ground. I checked their website and the products exists but doesnt seem to make such a claim.

 

still wondering about this. hopefully my question is clear?

 

i would way rather have a locker.
heres the video i watched of it working.

Interesting. I wonder how it would compare to an aussie locker

 

I missed this one but factory LSD one installed in 05-08 trucks will power truck with one wheel in air
