We want to thank you for the great sumosprings products. We installed them on our 08 Bounder and the changes were night and day. Better ride, handling, less sway etc etc. It rides like a different coach and we are extremely grateful. I would recommend sumosprings to everyone. And the installation was not bad at all. Did it myself in about an hour and a half.
Thanks Sumosprings.

Installed Sumo Springs on the front of my motor home. The passenger side was relatively easy. The drivers side bump stop nut is not welded in the frame. If you are not very mechanical inclined, pay a professional to do the installation. The Sumo Springs make a big difference. I recommend them. Will be ordering the back springs as well.

Great install on the front of my 2021 Ford F53 Chassis (22,000Lb) 39ft long Forest River Georgetown GT5 model 34H5
All went well on the install but folks you really need to sit down with someone who has never installed any of these SUMO Springs and have then try to understand the instructions.
You then will find out that the diagram/picture could be better and the directions of what side it is and the front of the motorhome.
The picture in the instructions may be clear to you but for us new folks it can be better.
The actual SUMO Springs do what they are advertised to do. Stabilize the side-to-side roll better and add some better cushioning on the bumps, cracks and holes in the roads.

Once I was able to free the factory bump stops the install was a breeze.

Before adding this product my motor home had a lot of sway when big trucks went past now that i have it on it has been a world of difference

They were shipped in a reasonable time frame, Easy to put on, and most of all change the way the coach handles on the road. Can drive with one hand now.
