    Abstract: A trailer hitch system for equalizing trailer loads and reducing trailer sway. The trailer hitch system may include spring bars that may extend from a hitch head. The spring bars may be attached to the trailer using rigid brackets that reduce swinging of the spring bars. The rigid brackets may include an upward extending portion for attaching to the trailer tongue, and a lateral extending portion for receiving the spring bars thereupon. Pins may be utilized to secure the spring bars on the lateral extending portion of the brackets. The pins may each include a spring loaded clip that is rotatably between an unlocked position and a locked position.

    Abstract: An adjustable height trailer hitch may include a shank portion configured and adapted to be installed into a hitch receiver. The hitch may further include a drop bar extending downwardly from the shank portion. The drop bar may further include a plurality of pin receiving holes formed in the drop bar. The hitch may further include a ball support member having a locking pin disposed in a locking-pin bore and an actuator pin disposed in an actuator bore. The hitch may further include a locking ring disposed in an annular groove of a cylindrical sidewall of the actuator bore. The locking ring may prevent backout of the actuator pin.

    Abstract: A weight distribution measurement system includes a portable measuring device configured to measure a linear distance and store a plurality of measurements. The portable measuring device is also configured to measure a first distance between a first location on a vehicle supported by an axle of the vehicle and a second location, wherein the first distance is measured prior to loading the vehicle. The portable measuring device is also configured to measure a second distance between the first location and the second location, wherein the second distance is measured after loading a vehicle. And the portable measuring device can measure a third distance between the first location and the second location, wherein the third distance is measured after loading a vehicle and after a weight distribution mechanism has been engaged, and then calculate the percent weight distribution over the axles of the vehicle using the portable measuring device and display the percent weight distribution.
