The "Hensley Bump" is an undesirable side effect of the converged link hitch design (found in both the original Hensley and the Propride 3P product). In short, the trailer can "run up" onto the tow vehicle in heavy braking situations. When the TV is stopping at a quicker rate then the TT, the pivot head of the hitch will slide to one side (as if in a turning maneuver). It will eventually hit rotating limit of the head (literally hitting metal stops) and produce a bump that resonates through the TV. You can google "Hensley Bump" for a more detailed explanation and there's some youtube vids out there showing the behavior.

When you have to slam the brakes, the TV is going to want to stop shorter then the TT and with a joint in-between them (Hensley), it's going to pivot and move.

I have a bars to chain type now and hate the bounce it give and the pulling over toward the passing big rig when big rigs pass.
