Weight distribution bars different number of links

It has been quite a few years since I used a standard WD hitch but if I remember correctly it was very common to have one bar much harder to snap up than the other. It had nothing to do with bent bars but some other reason that excapes me right now.

Regardless of the reason, I would not advise using different number of links on the bars. Keep the number the same on each side.
