Definitely a dramatic improvement over the stock equalizer. I have not taken it out on the highway, but in town, over rail road tracks and bumps, I can see the camper move more than it used to. The equalizer definitely let the spring work harder to absorb the bumps. I also noticed that when I make a tight turn, the camper no longer make those clunking noise. It definitely let the axles move more freely than they used to before the upgrade.
Seems to be work as advertise
