Bouncy F350 SRW

Posting this for a buddy of mine as he was asking what I thought. He has a '15 F350 CC,4x4, sb,6.7 srw, air bags and Lower Stable Loads and tows a 38' +/- TH. Truck weighs 8500 and TH at 15,500. Most recent scale ticket says he has a pin of 3100. So now the problem. When he goes over bumps (expansion joints) he says the truck has a pretty good bounce to point of being kinda "violent" he said. Has the lower Stable Loads engaged, about 50 lbs of air in bags. Trucks squats about 2". I was thinking he may have the same issue I did w/ my dually w/ the aux spring slap.

I won't be able to post any updates until next week and he said he won't have the TH out again for a few weeks. In the meantime, what's the consensus of his problem and solution to it?

TIA gang.

  • Expansion joints at bridges are a problem for everyone that tows anything. His situation is not unique. We all experience that! And being as heavy as he is, he's going to feel it more. You can soften the suspension all you want, but the tires are still going to take the same "hit" no matter what rides on them.

    This is another reason why I avoid interstate at all costs, as much as possible. Faster speeds, harder hits on the tires! All the bells and whistles in the world to make it more comfortable for the passenger won't change the blunt the tires takes.
  • Short bed truck, most likely the hitch is over the axle or behind. If it was moved to 2" ahead of axle, it would ride better.
