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.

Huge difference in driving quality between the stock bump stop and sumo springs. We went from bumpy ride and feeling every pot hole to better ride quality. Before the sumo springs every high wind areas we passed I have to slow down and manage the steering wheel continuously, After the install, it’s much stable and resists cross winds immediately and consistently adjusting the vehicle position in space. Probably the best investment I put on our 2020 Airstream Interstate 19.
