Description
SumoSprings® are a patented suspension product designed to enhance load carrying ability, stabilize sway, and improve overall driver control and ride comfort. They are maintenance free, do not leak air, and do not require airlines or compressors. SumoSprings® are manufactured in a variety of heights, diameters and densities to support multiple front and rear applications. They are manufactured from proprietary closed micro-cellular urethane providing a smooth and progressive spring rate with superior damping properties. Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles—proof of the craftsmanship that goes into every piece.

Chris Rounding –
SumoSprings have made our van handle much better – flatter through corners and less swaying over low speed bumps.
James Bradbury –
Easy order and install
Daniel J Foley –
Vast improvement in ride, stability and handling. Cornering extremely improved.
Fairly easy to install even with all the extra components tucked into the chassis.
Michael Hasenflu –
Made dramatic improvements
Jim Dyment –
When I first bought the RV it really swayed badly going up drive ways. Driving on the freeway was bad on cross winds and when semi’s. I needed something so I bought the sumo yellow what a difference. Love them
Glenn Sexton –
Seemed to help sway.

The package came sooner than I thought. I watched the video that Super Springs has for putting the springs on the chassis. The video made it look easy..I got my buddy and we followed the instructions on the video..In about 40 minutes with two total amateurs the Sumo Springs were on. The Wayfarer came with the Black Sumo springs. I replaced the Black with the Yellow Sump Spring. There is a big difference between the springs. So far I really like the Yellow Springs. I am waiting for the first of the year to come…Super Springs is supposed to have a new bolt-on helper leaf spring.
