F350 anti-sway bar

I recently changed pickups. I had a Silverado 2500 with airbags on the rear axle. Although it was overweight with the new-to-us camper we bought, it didn't roll from side to side when the airbags were inflated to 80 psi.

Fast forward. We replaced the Silverado with an F350 crew cab, long bed with V-10. Now the pickup is obviously up to the job of carrying the camper, but even with 80 psi in the airbags, it rolls from side to side quite a bit while underway.

I'm wondering whether adding an anti-sway bar to the rear axle will help. Thoughts?

Thanks
  • Roadmaster makes a very nice bolt on
    sway bar money well spend I have front
    and rear works great on my F250 :)
  • Thanks for all the replies. They give me a lot to consider. When I put the camper on the first time, I put 50 psi in the airbags "just because." When the truck did a bunch of rolling, I increased the pressure. Maybe I should have decreased instead.

    This rig is so new to me that I need to do some serious investigation into the matter. If there is a factory sway bar, perhaps it needs new bushings. I don't know how much the truck will squat if I put the minimum air in the airbags. So, I will take all your advice into consideration. I also look forward to hearing froum flipskid about how adding new bump stops works. Again, thank you all for your input. I'll report back when I know more!
  • i have a 04 f350 with a 1010 lance. i have air bags because i thought i would need them. i might for leveling the ride, but i dont even hit my top overloads yet. I currently have 30 psi when the camper is on. i am ordering some new bumb stops, not the stable's, but some generic ones that will work just fine. saves me some serious coin. Ill let you know how that works.
  • My first thought is that you are running too much bag pressure resulting in a bouncy ride. Upper and lower StableLoads will preload your overload springs and require very little bag pressure unless you tow something with a heavy hitch weight. I didn't need shocks until I went to the heavier 19.5" wheels, but my truck is two to four years newer than either of yours.
  • I would put a rear anti-sway bar at the very top of the list of any truck I hauled a camper on. There is a reason the are called "Anti-sway bars". If I still had sway, with tears running down my cheek (due to cost) I would look at stiffer sidewall tires.

    There are too many variables to state how much air you should put in air bags. It has been my experience only experimentation can determine that with each vehicle. I will add, with a split air filler setup, less sway will be encountered.

    I am an absolute believer that an anti-sway bar, stiff tire sidewalls contribute the most to reducing sway. The bigger in diameter of the anti-sway bar the better.

  • If you have the rear overload springs replace the stock bumper stops with torklift stable loads http://www.torklift.com/products/stableload.php

    My F350 with the Camper package came with rear anti-sway bars if yours doesn't have them get them.

    What tires are on it? they need to be load range E and be rated above 3150 (mine are 3750)

    How old are the shocks (oem are junk)you may need new beefier ones

    You Should not need to be running 80 psi in the bags if the truck is set up correctly My 1055 on my 350 runs fine at 30 psi
