Description

SuperSprings SumoSprings enhance your suspension. They increase comfort, level sag, reduce sway, protect cargo, and save money with maintenance-free performance. SumoSprings are manufactured from proprietary closed micro-cellular urethane that captures air inside millions of air pockets, providing a smooth and progressive spring rate, and will not leak and never requires airlines or compressors. SumoSprings are available in a variety of heights, diameters, and densities to support multiple front and rear applications.

SumoSprings available densities and styles:

* Blue urethane is -40 density--captures more air in the millions of micro-cellular bubbles, creating an air spring suitable for light and medium duty applications.
* Black urethane is -47 density--balances the amount of urethane and air bubbles to create an air spring suitable for light, medium, and heavy duty applications.
* Yellow urethane is -54 density--traps a smaller amount of air in the air spaces creating a stronger air spring suitable for medium and heavy duty applications.
* Solo--One-piece units attached on one side used as a replacement/upgrade to factory bump stops
* Maxim--One-piece units attached on top and bottom allows up to 50 percent expansion of original body height
* Rebel--2-piece units attached on top and bottom using separate male and female pieces allows unlimited travel
