Limited slip differential 20 v 21

[Joe Butcher]

That video is what prompted this thread.
I’ve been looking into if a g80 can replace it.
I’m wondering if the guy didn’t spin the wheels fast enough. The other rear wheel should have done something but it clearly did not
I went to a dealership and had the parts manager look up the axle for a 21 suburban. G86 was not listed but a g80 positraction was.

same dealer looked up the rear end by vin. It is a G86 limited slip

The g80 never played well the traction control. In a extended slip condition the system would overreact and defeat the ability of the locker. You had to turn the traction control to off to get the lockers full ability. The g86 style had a expensive additive that had to be added to prevent chatter in the turns......lots more metal on the magnet and the fluid from g86 clutch’s.
