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.

the difference these springs make is INCREDIBLE !!!
Rick Willis –
Installation was easy and straight forward. I really appreciated that everything was included- including the thread lock.
Driving the van, it is noticeably more stable and much more controlled in corners. Not as susceptible to wind sway. Very pleased!

Really satisfied by the quality and the design of your product. Complet installation as been done in 1 hours and a half without using any specialized tools.
And the results is amazing. I drove a truck loaded with tools for a service company. This is exactly what my truck needed.
Thanks again for your hard work and for your great service.
