Explanation of How Weight Distribution Systems Work

Question:

Can you explain to me why and how this unit works? As I see it, it all goes back to the 2 receiver and hitch.

The Pro Series RB2 Weight Distribution, part # 49570, and all weight distribution systems work to spread the tongue weight of the trailer to the vehicle and trailer axles and level the rear of the vehicle for safer towing. This is accomplished by using the leverage applied by the spring bars to transfer the weight. When weight is applied to the spring bars the spring bar is actually pulling down on the trailer frame at the attachment brackets and pushing up on the weight distribution head that is attached to the shank and trailer hitch. This pull-push condition transfers tongue weight to the axles on both the vehicle and trailer but does not reduce the amount of weight the vehicle must pull.

I am including links to FAQ pages on weight distribution systems.
