A locker is designed to assist when you only have 3 or two tires on the ground. Like v ditches, were you have to approach at an angle. Maybe going up a rock hill were you only have tracktion on the front tires and one rear.
I will say steps on a high tracktion surface can be done with no lockers given no uneven surfaces. You understand!!!!
Get lockers if you realy want to conqure tough areas without worries about what wheel will be receiving torque.
Allow your driveing to screw you up not the Truck.
