    • Q:

      will putting these on my truck help with the swaying at highway speed when i have my slide in camper on the truck. the truck is body lifted 3inches and sits on 35's any help would be wonderful.
      Asked on 2/16/2010 by bigcountry from thomasville Ga

      1 answer



        One reason for your truck swaying, could be the height of your truck and with the camper on the back, there is a larger surface area for the wind to hit. A set of air shocks may help a little bit with it, but most likely they will not fix the problem.
