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.

Excellent product! My Bronco don’t sag so much anymore, and I can’t notice it when not towing- drive normal, and it’s service free. Also this company got the best customer service in the business. If you have a long 14mm socket, you can install it in 30 minutes.

If you would want your Bronco to sag a little less I installed a hockey puck in place of the thickest spacer under the blue sumo springs, and still have about 1/2- 3/4” gap from the frame
