Suspension upgrade help.

I have a 17' F350 4x4, CC, LWB, SRW. I'm using Lower Stableloads, Air Lift 5000 bags and Nitto G2 295/65/20 tires. As is, this truck handle our 18' Lance 975 every bit as good as our old 16' F350 Dually and 17' Lance 1172 did. The new Ford Super Duty's are amazing trucks.

They'll work fine. Stableloads will stiffen up the springs and the Timbrens will hit at the same squish unless you re adjust them.
Fwiw, you can make homemade stable loads out of many things. I used plastic felling wedges. Fords are easy since you can just put wedges in and run a screw thru the hole in the spring.

I have a little bit different configuration on mine than the OP asked about but it works extremely well with my 2017 F350 and Northern Lite 8.11.

I have the upper stableloads, Airlift 5000 Ultimate airbags and my truck also has the camper package which means essentially on my one ton that it has the rear sway bar. I typically run my airbags at 45 lbs with the camper loaded and ready for travel. I do have the onboard compressor with WirelessAir remote so I can put different pressures on each side if needed but so far I have been able to keep both sides at 45 lbs and the camper is stable and level.

I have upper and lower stabilloads and AirLift bags on F350 SRW. The stable loads reduced sway and the air bags bring it back if pumped up high. I think I need a hefty anti sway bar in back and different shocks which also may help reduce front to back rocking

I started out with lower Stable Loads on my GMC 2500HD, they were awesome reducing sway. I almost always tow a 16' trailer with a side by side ATV (loaded with cooler, firewood, 20 gallons gas, etc), so I added the heavy duty Timbrens. Absolutely no complaints with either addition.

On my SRW GMC I added heavy duty Timberns and lower stable loads. They work well together. I also added a helwig sway bar, big improvement. I carry a Hosts Cascade. My GMC is a 3500. Hope this helps. Eddie

We have a Ram 3500 dually and put on upper Stableloads to start. That helped somewhat with sag and such.
Then we added the Timbrens and it made a very noticeable difference in turns/cornering. Took away that side to side rocking. Much better!

I have both timbrens and lower stableloads on a 2011 F-250 they work really well carrying my Lance 825. The stableloads take a lot of the sway out when cornering. I just traded the 825 for a new Northern lite 811 so I can't wait to see how it will handle the new camper.

I'd be interested as well. I have a 2017 F250 and have purchased (not installed) Timberlins.

Here's what my stock rear spring pack looks like:


Due to the lack of leaf springs I was under the impression that only LOWER stable loads are available for this model.

I'm interested in reading the replies also.
