Conventional Hitches

Trailer sway is caused by a rocking action at the ball (“B”) when the trailer is under the influence of side winds caused by passing traffic or accidentally driving onto the shoulder of the road. The rocking action is a result of steering corrections made by the driver trying to get his trailer in line.

Trailers pulled with a conventional hitch experience this “tail wagging the dog” sensation due to simple leverage factors. With the pivot point at the ball, 

extending 8 to 10 inches beyond the bumper, the long lever arm from the vehicle’s rear wheels (“A”) to the ball allows the trailer movement to whip the vehicle back and forth, causing violent sway conditions in the trailer.  

The trailer is now driving the vehicle; the driver is unable to gain control through the vehicle’s steering, resulting in damage to both vehicle, trailer or possible personal injury.  Sway controls attempt to restrict sway by controlling movement at the ball. Under hazardous or emergency conditions, the sway controls can cause accidents. In fact, most sway control manufacturers recommend disconnecting them under “adverse weather conditions”—just when you would seem to need them most.

PullRite Trailer Towing System

The PullRite eliminates sway! Using no add-on sway controls the PullRite operates like an upside-down 5th wheel, pulling your standard travel trailer from a point immediately behind the axle housing (“A”). How can this be? 

The PullRite’s ball mount has no moving parts, consequently, when the equalizing bars are fit into the ball mount, the side-to-side movement is locked out, so the trailer can no longer pivot on the ball (“B”). 

Using a draw bar that, in effect, extends the trailer tongue, the turning action is forced into motion at a point directly behind the axle (“A”). With the turning action at the axle and no movement at the ball (“B”), side pressures (18 wheelers, wind) merely "try to push the vehicle sideways, steering is not affected so sway can not occur.
