Weight equalizer hitch

I have read all about these (50+ sites) but I question their ability to transfer weight any different than a hitch bolted to the bumper frame if the ball distance to axle remains unchanged. Both make the frame behave as a single lever regardless to were they are mounted. You could mount a rear hitch with long non flexing arms to the front of the frame and still won't change a thing...a single lever is a single lever. I do see the load carrying and pulling improving simply because bolts are on shear and on a stronger anchor point. Please enlighten me with your thoughts and not by simply repeating what someone else said.
Thanks.
  • I think what you're not understanding is that with a weight distributing hitch, the trailer tongue is not just resting on the hitch ball like it is without one.
    The spring bars of the WDH swivel left and right to allow turns but they don't freely swivel up and down. There is tension on them. They're trying to force the whole truck/trailer set into an arc as viewed from the side.
    When you crest the top of a hill the WDH will not exert much pressure (or any if the angle is steep enough). When you approach a steep upward ramp, the hitch will be resisting the flex that puts on it.

    They do transfer weight, mechanically. As others have shown, you can measure it on a scale.
  • The spring bars are a linear extension of the truck's chassis that reach beyond the ball (lever point). The chains act as if you were pinching this extension toward the trailer's chassis to use the lever point to reverse the action of the tongue weight on the lever point. The lever point works both ways. If you pinch hard enough as in tightening the chains with stiff enough bars, you can lift the rear wheels of the truck off the ground.
