I ordered these to help reduce the rolling (tilting) of my 18' travel trailer that I use off-road. Also, I am hoping it will absorb some of the shock. I have added some photos of before and after installation. The installation was simple, I used 5/16" sheet metal screws instead of the bolts supplied. Time will tell if they work as expected. As you can see from the photos, I have previously added an Etrailers shock mount kit to my axle. I made custom lower mounts that I welded to the axle and used the supplied upper mounts.

I made some brackets to bolt to the frame. Now I have 100% contact with the Sumo Springs. The are working extremely well!

Easy install. It took me approximately 3 hours for the entire project. That's cleaning a few things up also. I did not notice much difference in "body roll". Honestly,, I never had much before. Now, anytime going over rougher roads, railroad tracks, etc.... That was a big difference. It took a lot of that movement out. I hardly knew the trailer was going over it. I installed these on a 5th wheel.

Worked really well, definitely smoothed out the ride. We are finding significantly less chaos with the equipment in the trailer. The only complaint I would have is trying to use the Sumo Spring for very small enclosed trailers. The STEEL MOUNT was too tall, to meet the relaxed position height, so we cut 1" out of the mount and re-welded together, and repainted. But other than the additional modification it worked great.

I purchased these for a 2022 Forest River Wolf Pup 16BHS. During the process of replacing the leaf springs I also had these SumoSprings installed to help with a smoother ride and to increase the longevity of the leaf springs. One year later everything is still working as intended. Would definitely recommend this product to anyone looking for a smoother ride or to increase the life of your leaf springs.
