Are you an RV owner? Do you own a truck/van used for recreational purposes such as towing a boat or trailer? Are you looking for a smoother ride and want to damp road noise and shock? Do you take your vehicle over rough terrain or off-road? If so, then this is the right item for you.

SumoSprings® is 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.

SumoSprings are not made from rubber. They are a progressive spring with a very soft initial engagement. That means that as more weight is added, the harder they get and the more they push back, providing support and control when you need it without affecting the factory ride when unloaded. These are suspension enhancements built to create a better journey. Manufactured from our micro-cellular polyurethane, they are designed to reduce rear-end sag, decrease vibration, stabilize sway, and soften harsh rebounds.
