Super Springs

Just heard about a product called Super Springs. A simple to install "bumper" solution to help reduce sway and bounce on RVs.

On our 25' class C with a sprinter chassis - the ride is OK overall however we do get a lot of sway turning into driveways for gas / stops. Kind of reminds me of the tilt a whirl carnival ride sometimes

Anyone out there install these on a class C? If so how did they perform?

Are you possibly referring to Sumo Springs. If so I installed them on the rear of my 23TR and it made a huge difference with sway from passing/meeting trucks to driveway curbs. I paid to have them installed. Took about 30 minutes and $80 If I recall.

Ron installed Sumo Springs (bump stop) front rear of our Axis. He is happy with the way the motorhome handles with them.

SUMO’s work
Many on this Forum (including me) have installed for reduced sway and porpoising

I don’t think they are made for your 5er.

Actually they might work well on a 5th wheel.
You will have to have the capability vof mounting them yourself and possibly making the mounts. They have a builder series just for that.
I put a set on my wife's 1951 Ford pickup, and we love em.
