How Does a Load Distribution Hitch Work?
When towing a heavy load, a weight distribution hitch is a necessity. This device helps stabilize the load, cutting down on trailer sway. A tow vehicle can become quite unsafe if the wrong type of hitch is used.

Standard Hitches

A standard trailer hitch is bolted directly to the frame of the car or truck towing the trailer. When using a standard trailer hitch, the majority of the trailer tongue weight is transferred to the rear axle of the tow vehicle. This lowers the back end of the tow vehicle and raises the front. This can lead to decreased steering performance as well as braking issues. Trailer sway is also an issue.
Load Distribution Hitches
-
A load distribution hitch, or weight distribution hitch as they are commonly called, uses spring bars that apply leverage between the trailer and the tow vehicle. These spring bars help spread the weight that is resting on the rear of the vehicle to the axles of the towing vehicle and the trailer.

Benefits Of Load Distribution Hitches
-
Distributing the weight along the axles levels off the load, and the performance of the tow vehicle is significantly improved. A weight distributing hitch is necessary if the trailer's weight is greater than 50 percent of the tow vehicle's weight.
How They Work
-
A load distribution system consists of a shank that plugs into the receiver. A head assembly is then mounted onto the shank; this provides a platform for the spring bars and hitch ball. The spring bars run from the head assembly to a pair of chains. The chains hang from the trailer and, when attached, create tension on the spring bars. When the tongue weight pushes down on the bars, these chains help pull the bars back up. The spring bars then push up on the head assembly which distributes the weight between the axles.
