Centerpoint suspension question

Have had trailair suspension for several years but lately been wondering if one should add more air when things bounce around in the trailer or go the other direction?
Anyone with experience in this sound off.
  • I only have one fill gauge. 5#per thousand on the axles. Made a difference in stuff moving around, but really rough roads will still shake things up inside.
  • I have it and I love the whole system, both centerpoint and trailair, I believe they add to the lifespan of my fiver and it's contents. The first year going to Florida when we made a pit-stop I opened a bottle of water and left it half full in the sink and forgot about it, four hours later it was sitting where I left it when we stopped for the night still half full and up-right, I wouldn't have a fiver without them!! I keep mine at 55psi.
  • According to the Centerpoint folks you need to set the arms on each side of the bag with enough pressure so they are parallel with each other. To do this properly you need to have each side plumbed separately because it is highly likely one side of your fiver will weigh more than the other. I installed a set this spring that way and they certainly made a difference in the ride of the trailer. When they are parallel the distance between them should be about 5". I have a pressure gauge for each side and the road side takes about 10 more pounds of pressure to get the proper distance between the arms than the curb side.
  • We tried everything and every setting to reduce the bounce when we had Centerpoint, nothing worked....when we order or new rig we went with Mor Ryde IS...will never go back...
  • You need to find out the correct measurement between the air bags. It is something like 5 to 6". I think it is 5 lbs per thousand lbs of weight on the axles. I have not measured but use 65 lbs of air pressure.

  • We have trailair suspension and have no problems with things bouncing around. Just keep it aired up to the weight on your axles.
