4.16s will be perfect for your setup if you never wish to go bigger than a 31 inch tyre on your rig. They are made by Trail Tough both of them. They are good quality and you should have no hesitation running them in the bunny rig. I run the 4.9s in my sierra Chris and never ever had a problem.
The auto locker only activates when it receives power from the pinion/tailshaft end I.E from the motor. If the transfer case and gearbox is in neutral and you are towing then the wheels are driving the rear diff and no locking will occur so it will be fine.
