Questions & Answers
They're fine as bump stops, but they're not built to increase the vehicle's weight capacity.
They're on our Alliance 372RK, and I like them a lot. You install one set on each axle, which significantly reduces sway and softens the ride.
The TSS- 107- The 40 comes with everything you'll need to get the unit up and running.
They might be a little too powerful for such a light trailer. I used a 12,000-pounder for mine. fifth wheel recreational vehicle

It made a noticeable difference when we installed it on our 27BHS travel trailer. The bucking sensation is now greatly reduced when traveling over train tracks and road undulations. Keep in mind that I'm towing the camper with a 2019 Ford F350 dually equipped with a WDH. We wish we'd done this from the start. It was well worth the money. In less than an hour, I had them mounted on the camper.
My 5th wheel trailer suspension lacks shock absorbers, allowing road bumps to bounce the trailer, resulting in harsh chucking forces (forward and backward) on my truck. The occupants of the truck were extremely uncomfortable as a result of this. I had read positive feedback from other RVers who had installed these and had good results, so I decided to give them a try in the hopes of getting some relief. It was fairly simple to set up. It was simple to follow the directions. It took about an hour for me to complete this task. The end result was incredible. The abrasive chucking was reduced to pushes that could be tolerated.
IDK. They are simple to set up. I don't know if they actually improve the ride because I don't ride in my trailer; we'll see how much things move inside during my summer travels. But it was reasonably priced, so I decided to give it a try. Friends raved about it.
These were installed on my 17' travel trailer to aid in the bouncing of the new leaf springs, but I believe they are far too stiff. These definitely help the new leaf springs after a few road trips, but they seem to stiffen the ride for the travel trailer, worsening the moving earthquake inside the trailer. Because I won't be able to return them, I'm going to cut them in half and use them as bump stops. If they don't work, they're a bit pricey.
And it's simple to set up. My 2017 Keystone Avalanche 5th wheel was outfitted with these Sumo Springs. I can't express how much of a difference they make in trailer vibration and road handling on my 2019 Ram 2500, which has them installed front and rear.
Bonus points for surprising me with the hardware needed to reroute the gas line beneath the RV.
On the road, it really helps to keep the rv stable.
It's extremely simple to set up. The LP gas line was shifted with all of the necessary hardware. I haven't towed with them installed yet, so I'll post an update once I do.
