I have had an Aussie locker in the rear of my 85 4runner for the last 3 years or so and it works nicer than the lock rite which I ran for 5 years. I am running 33x13.5 Toyo MT's and have a Marlin 4.7:1 transfer case. I run a Toyota electric locker in the front so my traveling on snow covered roads is a little more predictable.
