Is it better than an open diff? Sure, of course, anything is. Is it what I want? No, not even close. Will it ever give a true 50/50 torque split? Only when both wheels have the same traction. Is it what I want? Nope, not at all.
IMO, since an actual locker, that will provide a 50/50 split, that will outperform this every time, period, was only 400 bucks, an inferior product is a no go for me.
I'm not paying 700 dollars, for a compromise of what I want, and going through all trouble of tearing the front chunk out to install something that is a pale shadow of what I want, no thanks. My Dana 60 Spartan locker was 330 bucks.
But, that's my opinion. I'd like to see someone try it, I'd like to see vid. I'm also of the opinion that the rear G80 is worthless too, and plenty of people here are happy with theirs, so opinions are worth what you pay for them
