[Chance]

As stated before in other thread, the drop down extension adds to the “moment arm” length during braking; which just happens to create a torque in OPPOSITE direction that a weight distribution hitch rotates a receiver.

Notice that many/most receivers have a higher weight distribution capacity versus when same receiver is used in load carrying applications. It’s not a simple stress analysis, but one of the significant differences is that the point of failure you guys are seeing would be stressed much differently. Instead of receiver being pulled away from chassis rails at very end where it it weakest, a WD application would push the receiver into chassis at very end (or at least not pull them apart as much).

Just like WD increases capacity, it’s understandable that a drop extension would have opposite effect. The problem I see is that consumers who buy different components can’t be expected to take all these variables into account. Each piece may have a different rating, but when combined the total can be LOWER than the weakest individual component.
