I have had three different setups on mine, and all of them tend to bounce a bit. But I also have 10 ply tires and stiff suspenion up front. I have retrofitted a set, bought a set, and also tried factory '13 heads, and the same '13 heads with EVOX projectors. They all bounce. I have taken every set apart and made sure everything was good and tight everywhere...... the only thing I can come up with is the beam adjustment bracket has a bit of wiggle room. If you take a light apart and tap on the black bracket, it definitely moves just a hair. I don't think we notice it on halogen lamps because the beam is everywhere. It's just my opinion, but I feel a better way to keep the adjustment bracket in place would help.
