Trailer SumoSprings

SuperSprings Product Bulletin 6 Comments

SuperSprings International, Inc. (Carpinteria, California) announced Trailer SumoSprings for various trailers. Trailer SumoSprings utilize the same micro-cellular air springs as SumoSprings. They mount above the trailer leaf spring assemblies and create a cushion between the axle and trailer frame. Trailer SumoSprings reduce wear and tear on body-frames, windows, doors, closets, mounted TV’s, and other components by minimizing bounce, hop, sway, and road shock associated with most tow-able RV’s. Reduced sway and bounce in the trailer results in increased driver control, ride comfort, reduced maintenance costs, and reduced overall cost of trailer ownership. They are maintenance free, do not leak air, and do not require airlines or compressors. Trailer SumoSprings are available for a variety of trailers using Lippert Components, Inc. axles with a GAWR between 4,000 and 8,000 pounds.

“Once the Trailer SumoSprings were installed, I immediately felt a difference in the steadiness and smoothness on the backend. I experienced all different types of road surfaces on the roadway, from smooth to extremely rough. The drive was smooth and steady; it felt safe. This made it a very enjoyable and stress free drive.” -Cameron Sanchez, Driver/Owner 2013 Dutchman Denali Travel Trailer.

  1. Wondering if these will work with a mobile home axle used for a trailer – leaf springs are a bit weak and the design of the trailer bottoms out the load immediately. Would you replace the leaf springs and then add the sumo trailer spring?

    1. Hey Art, I like your creative thinking! We have had customers use SumoSprings for various “non-conventional” applications. If you would like to get more details from one of our engineers, please send in some pictures of your trailer spring pack and axle to [email protected]. Thanks for the inquiry!

  2. Would you suggest the Sumosprings be put on both trailer axles? For a total of 4 springs? Say on a 12,000 + 5th wheel

  3. Hello,
    I have a 5th wheel that is right at 16,000 pounds. Would the TSS-107-40 help? I notice the product is Blue foam and I was wondering if Black would be better and if there is that option.

    1. Jay,

      Thank you for the your question. The TSS-107-40 is the strongest trailer SumoSprings that we have currently. This application is for a spring over the axle configuration. Is this a single axle application, we do recommend putting a kit on each axle. The Trailer SumoSprings will help with hauling of your 5th wheel, they are designed to help reduce the sway of the vehicle as well as sag, providing the driver with greater drive control and ride comfort. Attached below is a video of this kit being installed and tested, so that you can see how this will help you out.

      Please let me know if you have any questions.
