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.

This product surpassed all expectations! Greatly reduced body roll, hits potholes like a half ton, and got rid of all the suspension sag from the plow. Easy 20 minute install. Extremely happy with this product, I’ll be ordering the Sumo rears very soon.

Absolutely Amazing!!!!!!!!! Couldn’t believe how much better the truck rides. Makes my daily commute of 250 miles so much more enjoyable. The sumo spring are the best money I have spent so far on this truck and I have over $25,000 in upgrades on my truck. Honestly I have been telling everyone about them! Thank you for a great product and excellent customer service!! Any wait to put them on my travel trailer!
