Sag - Timbrens, Stable loads (upper or lowers?), or ???

If you have the upper overload spring, the StableLoad taller contact pads will make a big difference. If you need more (my camper is heavier than yours), the StableLoad wedges on the bottom spring can be added later. I'm close to you and could show you my setup. If you do not have the upper overload spring, you will need to add a supplemental spring (SuperSprings, WorkRites or Timbrems) first before making additional changes.

Stop at one of the DOT scales and get your axle weights. You will want to know how close you are to your tire capacity.

My 2 cents.... Our last F350 was a 2003 with a 2950 dry weight camper on it. We used air bags. They worked Ok. I have Timbrens on my current truck and I prefer the ease of operation of the Timbrens, although they won't eliminate as much sag as other alternatives.

I began with the Timbrens, but due to the mounting locations inboard of the springs, sway was increased. This was improved by using Energy Suspension Bump Stops on the overloads. This was before Stable Loads existed. I would begin with the upper Stable Loads.

Thanks all for your responses so far. I have to admit, I thought I might have received more responses then I did. Bedlam, yes I would like to take you up on your offer to see your setup. I will PM you about this.

I haven't been on here very long, but I think it is because everyone needs a break on this topic. It was just discussed in length about 3 times in as many weeks. Plus, I did a search and found this discussion comes up quite often, with the same results each discussion.

Be happy you haven't had the typical responses of:

You're overloaded on that SRW.
Go to a scale and get weighed.
You need a bigger truck.
You need 19.5 wheels.
You should have bought a truck that doesn't sag.
Fords have weak frames.

If you are wanting to try Stableloads, start with the lower ones for sure. I like mine and they made a significant improvement in sag and a more stable ride.

Thanks for the response. As you can see from the few above responses, there are mixed thoughts whether to go with the upper or lower Stableloads. Would you please share with me why you have Stableloads in addition to airlift bags? I would be curious to know, did you installed your Stableloads first or the airlift bags first? I truly appreciate your, and everyone else's, help with this. Hopefully it will save me some time, frustration, and $$. Thanks again.

I installed the lower quick disconnect stableloads first. They made a huge difference and greatly reduced sag. They also tightened up the rear suspension so it felt more controlled. Without them there was a bunch of suspension travel and I felt it bottom out on the factory jounce bumpers a few times.
The lower stableloads are going to make the most difference vs the uppers. The lowers take up the slack to your lower overload spring which is very thick. The uppers stableloads use the smaller overload spring at the top of your spring pack. I'm sure that will help when used in conjunction with the lowers but I wouldn't start with the uppers.
I had a disdain for air bags. I used them before. I did not like the requirement of always running with air pressure even when unloaded. I found the Airlift bags that now come with internal jounce bumpers eliminating the requirement to have air pressure even when empty. So far I like them. I do not need a bunch of air pressure when carrying my TC, although I am on the lighter side. The bags are the icing on the cake and allow me set the ride height where I want and add just that final touch of stability and load capacity.
It's a good, better, best kind of deal is how I'd put it. I'll just restate the advice that was given to me....try one thing out at a time. No need to do it all at once, see how it feels and works for you and your setup.
I am positive that Timbrens or anything like it are not for me. I know I wouldn't like them at all. I have tried helper springs in the past, albeit not on this truck and not carrying a TC. But they all destroyed the ride of the truck when empty. If you never unloaded, then those would probably be best. It's all a compromise in one way or another.
Man that got long winded. Basically I chose what I did because when I am not loaded or hauling, there is no effect on my suspension with the airbags at 0 pressure and the stableloads in their disconnected setting. I like that. But when I am loaded, the combo works very well.

Like my Timbrens
