Weight Distribution (WD) Hitch --- How it Works

Here is another way we could state it even more simply:

A weight distribution system enables a tow vehicle to more effectively handle the tongue weight of a trailer by removing some of the load from the tow vehicle's rear axle and distributing it to the tow vehicle's front axle and the trailer's axle(s). A weight distribution system also increases the capacity of the receiver. Note: When the WD system is engaged the actual tongue weight does not change.
