Stop in for a cup of coffee

First time Mopar showing right there. I do have a positive traction device in my Suburban (14 bolt full float). It is a Lock-rite, which is a brand name as you may know. So I guess what I'm trying to figure out is besides a shuregrip, which must be OEM Mopar, are there any other non one wheel spinning aftermarket traction devices for the 8.25? Don't want limited slip.
IDK why you are opposed to a sure-grip. It performs using the same principles as a “Posi”.

There are no other options unless you want to install a computer controlled brake-lock differential system.
