Suspension mods and towing...my experience

So back in July I purchased my first Dually ( used 2011 F350 Crew cab, long bed 4x4 with the 6.7L Diesel with camper package) and promptly set about getting it ready to carry my Lance 1055 and tow my Sundowner Valulite 727 3 Horse slant load trailer.

First thing I did was add upper stable loads and a superhitch, I already had the super truss from my SRW. It was ok but too much squat and sway with just the camper so I added in lower stable loads.



Great ride with just the camper but with the horse trailer hooked up I was just nose high.



So with the need to be able to level and the fact that I some times haul just one horse and other times two but most of the time I run with out a trailer I decided on Airlift Loadlifter 5000 extreme airbags which can be run at zero psi due to inner bag snubbers.



This weekend we drove 100 miles each way to a 2 day riding clinic. One pass some bumpy freeway, two lane windy canyon roads and a small twisty rural road to the horse facility and onto some steep dirt roads to the barn area. I had 30 pounds in the bags. We sat level, no sway and the ride was super over all surfaces.







This is how it sits unloaded with the bags at 30psi and the lower stable loads engaged


Oh and we stopped at the CAT Scales, Full fuel, Full Water and propane, two Adults 3 dogs, one horse in the trailer with tack and hay.



Quite the load
but the ride was great the handling was great and the 6.7L diesel pulled like there was nothing hooked up to it.
  • I've been able to offload 2/3 of the tongue weight to axles other than the rear of the tow vehicle using a WDH - To do that, you really need to crank the torsion bars. I comfortably half the tongue wight applied to the rear axle when using a WDH.

    How you load trailer also makes a big difference on how much tongue weight you will have. Now that I have the 5-battery PowerArmor Solar box on the tongue, it has added to my TW. I also have the ability to carry 84 gallons of water in my enclosed trailer just forward of the tandem axles - Although I usually wait to fill up until I am close to my dry camp location, this also adds to the TW.
  • I too would like to see a comparison with actual weights with and without the bars.

  • Nice to see it all working.
    Was the weight taken with WD bars on?
    Would be interesting to compare to actual weights without the bars.
  • I am a firm believer in most trucks benefiting from airbags and a big sway bar. Almost a must. I am sure you can do okay without them, but I think they are worth while. I recently bought a DRW that has upper and lower OEM overloads, with Torklifts on the top. No sway bar or air bags. I would be pleasantly surprised if the sway bar and airbags are not needed. My TC is 4200 pounds and I only flat tow.

    I love the fact your airbags can be run at 0 psi if you are unladen. Wish my airbags were like that. Would make the truck ride a heck of a lot nicer. As is I have to have something like 7 psi in them minimum, and I can feel the difference.

    I run the same bags. I had a set of the Firestone Ride Rites before that worked great but the ride suffered loaded and unloaded.

    Now I can run 60lbs and the ride is much better.

  • Those same suspension mods worked great on my F250. The Firestone bags I had required some pressure since they did not have internal jounce stops. I have no need for these mods at this point with my new truck, but we'll see what happens when I drop an additional ton on the rear in the next couple of years.
  • I appreciate your post. It provides an incite as to what may be required with the equipment you have.
