Helper springs or air bags?

Hi all - I have a 2019 F150 3.5l EB w/6.5' box, and a 24' Coachmen Apex BH. The rig tows fine and I have good WD, but am considering helper springs or air bags to help with the slight sag I have. I have also read that helper springs can aid in sway control, and I am curious of its validity. I don't have sway issues, but naturally a strong cross wind can lead to some white knuckles.

I would appreciate any opinions from those with experience with either.

Thank you in advance!

The problem with air bags, you will need a air compressor, a controller in the cab, (to adjust the bags hight) and the air bags with mounts. Then you have to hook it all up. I removed my bump stops and installed Timbren Suspension System. It took less than a hour to install. The bottom of the timber sits one inch above the axle so it will not change the ride of my truck. Once I load the 5th wheel, my truck squats a little over a inch. It is more stable side to side and no maintenance required.


    You don't "need" anything but a basic airbag kit and there is zero maintenance required. You musnt have had airbags before.
    Although a little compressor or even a decent bike pump is handy to air down after you drop the camper for bobtail driving.

    Having a fully automated system is nice but not needed. Run the valves back to the rear bumper and use a bike pump. Unless you are airing them up and down several times a day, it's not a huge imposition. They don't hold a lot of air. You still have to worry about leaks over time.

    That said, we went with sumosprings on our F250. 1 bolt per side. Biggest issue was getting the old rusty bolt out. On a newer truck without rust, should be a 15-20min job.

    They are progressive, so unloaded, they don't create a harsh ride.

    I probably have a little less than 1" of space between the Timbrens and axle unloaded, and it settles down with a heavy load. I think it improves the heavily loaded ride quite a bit without being overly harsh. About $200 and zero maintenance.

    On a Ram 2500 specifically they also ride outside of the coil springs so they effectively widen out the suspension on the axle.
  • Quick and inexpensive. Find an old fashioned spring shop and have them add a leaf. It will raise your unloaded rear ride height.

  • On various light duty trucks, I've used helper springs and Timbrens. The helper springs made the unloaded ride a bit rougher, but not bad, and they worked outstanding for towing and stabilization. Timbrens caused my Ram 1500 to have a jarring ride that was completely undesirable. I won't consider them again in a light duty application. Another option is Sumo Springs bump stops. I've never heard a bad thing about them.
  • Helper springs and timbrens are full time support. Airbags can be easily adjusted for the load, or no load at all.

  • Quit finding solutions to problems that don’t exist and go camping.
