SuperSprings SSR-204-40 Details

SumoSpring Solo

The Solo Sumospring is a one piece component that is fixed to one side, used to replace or upgrade the vehicles factory bump stops. SumoSprings Solo is a one-piece, homogenous unit attached on only one side via various mechanisms. The Solo is manufactured in a variety of heights, diameters and densities to support multiple applications.

SumoSpring Solo

All SumoSprings are manufactured from proprietary closed microcellular urethane which yields a combination of uniquely distinctive properties. The materials density, tensile strength, elongation, tear resistance, rebound, and compression characteristics have been designed specifically to produce a smooth ride and provide additional load support.


Greater resistance with heavier loads = progressive load control


SumoSprings Helper Springs: Features & Benefits

  • Compresses up to 80% of their original height with full memory rebound
  • Expands up to 50% of their original height when connected both at the top and bottom
  • Easier initial compress allowing softer engagement; greater resistance with heavier loads = progressive load control
  • Will never leak and cause a loss of performance
  • Minimal lateral expansion under load will allow for operation in confined spaces
  • Highly resistant to oils, salts and UV rays
  • Temperature range of -25°F and 200°F
  • Maintenance free
  • Designed to “fit-it-and-forget-it”
  • Manufactured in the USA


SumoSpring Densities

In addition to the above mounting styles, SumoSprings are also available in three densities. SumoSpring helper springs densities are distinguished according to color as shown below, ranging from light and medium, to heavy duty. When multiple densities are available, pick the density that best suits your needs and ride preferences.

sumospring light and medium duty

The Blue-40 density traps more air in the millions of micro-cellular bubbles, making an air spring sufficient for light and medium duty performance.

BLUE-40

sumo springs - light, medium, heavy duty

The Black-47 density evenly distributes the amount of urethane and air bubbles to produce an air spring sufficient for light, medium, and heavy duty performance.

BLACK-47

sumo springs medium and heavy duty

The Yellow-54 density captures a smaller amount of air in the air spaces making a harder air spring sufficient for medium and heavy duty performance.

SuperSprings

SuperSprings International was founded in 1996 and has developed a patented line of self-adjusting suspension stabilizers that solve many of the handling and suspension problems associated with loads carried by passenger vans, pickup trucks, minivans, and SUVs.

SuperSprings Internationals products give users extra loading and towing capacity and prevent rear-end sag without hardening the ride on vehicles having leaf spring rear suspension systems.

SuperSprings was developed for the American market with production initially established in California to serve the market on the West Coast. Marketing efforts have continued to expand and SuperSprings Helper Springs and SuperSway sway control are now distributed through a national dealer and distributor network throughout North America.

Product applications for SuperSprings have evolved from being solely for pickup trucks to a broad cross section of vehicles including SUVs, 15 passenger vans, minivans, and RVs including Class C motor homes and campers. SuperSprings have also been accepted by large-scale manufacturers in the van conversion business.
