Blue -40 density captures more air in the millions of micro-cellular bubbles, creating an air spring suitable for light and medium duty applications.
Black -47 density balances the amount of urethane and air bubbles to create an air spring suitable for light, medium, and heavy duty applications.
Yellow -54 density traps a smaller amount of air in the air spaces creating a stronger air spring suitable for medium and heavy duty applications.

SumoSprings are a great solution for individuals needing suspension enhancement, as well as fleets looking to increase suspension abilities, provide safer ride control, and reduce the overall costs of vehicle maintenance. Fleet applications include: buses, delivery and freight, law enforcement, and more.
SumoSprings absorb harsh bumps and jolts to provide a smooth ride over uneven surfaces, highway joints, and other rough terrain.
By reducing harsh movements, SumoSprings give drivers better control of their vehicle. This increases safety and makes for more comfortable travel.
SumoSprings have a progressive spring rate. They start to compress smoothly with less resistance and provide greater resistance as they compress further.
SumoSprings increase comfort and control, help stabilize sway, and level loads. This makes SumoSprings a unique and complete suspension solution.
