Abstract
A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar having a modulus of elasticity, the moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a tension member comprising a top end configured to be supported by a frame member of the trailer, and a bottom end configured to support the rearward end of the moment bar; wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle; and wherein the modulus of elasticity is low enough that an adjustment range for the moment bar is greater than 0.5 inches is disclosed.
