Responding to customer requests and feedback was the motivation for producing the world’s first and only “airless airbag” suspension system for trucks and vans –SumoSprings.

SumoSprings-Rear SumoSprings are manufactured from an advanced high grade, closed cell polyurethane foam; ideal for the tough truck underbody environment. The product underwent testing in extreme conditions ranging from blistering US desert summer days to the frigid Canadian winter nights. Combining heavy loads with extreme terrain and temperature conditions over eighteen months of testing ensures their performance in any similar conditions our customers might encounter.

  • Highest Quality Polyurethane Available Delivering Unsurpassed Dynamic Performance
  • High Compression Rate with Full Memory Rebound
  • Compressible up to 70% of their Original Height Making them Ideal for High Dynamic Loading Versus the Typical 20% Compression for Material used by Other Manufacturers
  • Extremely Durable Material with Excellent Abrasion, Cut Resistance and Low temperature Flexibility
  • Engineered Surface Profile Provides Minimal Transverse Expansion – Unlike an Air Inflated Product which Expands Laterally when Compressed, the SumoSprings Compresses in on Itself when Under Load
  • Leak Proof, Rupture Proof, Maintenance Free Load Support
  • Capable of Supporting Loads from 3,000 to 10,0000 lbs. – Load Rating is per Pair – Never Exceed Your Vehicle’s Gross Vehicle Weight Rating (GVWR)

Front SumoSprings

For trucks with snow plows, winches and other front-mounted accessories.

Product Description

SumoSprings - Front Drawing All SumoSprings utilize patented micro-cellular polyurethane foam formulated with exclusive additives. The resulting combination of exclusive raw material and engineering design produces a graduated spring rate curve which results in progressive compression under load and variable road conditions. This produces a smooth ride and provides additional load support.

Features & Benefits

Manufactured in a proprietary casting process the finished material possesses the following properties:

• The highest quality polyurethane available delivering unsurpassed dynamic performance.

• High compression rate with full memory rebound.

Front Sumo Springs

SumoSprings are compressible up to 70% of their original height making them ideal for high dynamic loading versus the typical 20% compression for material used by other manufacturers

• Specifically designed and formulated for the tough truck underbody environment

• Extremely durable material with excellent abrasion, cut resistance and low temperature flexibility.

• Engineered surface profile provides minimal transverse expansion – unlike an air inflated product which expands laterally when compressed, the SumoSprings compresses in on itself when under load.

• Patent pending

Front SumoSprings – permits a far smoother load engagement than other products. More than a mere bump stop, this variable rate spring with load capacities of up to 3,000 pounds* eliminates the unforgiving “banging” effect produced by similar front-mounted products. Front SumoSprings are ideal for snow plow, winch and heavy duty replacement bumper applications. They will maintain the original factory ride and only provide additional support when needed. The kits ship complete with all mounting hardware required for a quick, easy installation – typically less than 30 minutes.

All SumoSprings kits are manufactured and assembled in the USA.

*Load rating is per pair – Never exceed your vehicle Gross Vehicle Weight Rating (GVWR)

Rear SumoSprings > Airbag Replacements

Leaking Airbags?

Eliminate leaking airbags by installing replacement SumoSprings bellows that are LEAK PROOF, MAINTENANCE FREE and provide you ‘fit it and forget it’ peace of mind. SumoSprings

SumoSprings SumoSprings rear suspension systems consist of two primary components; the steel bracket attachment system and the microcellular foam airsprings, airbags or bellows (photo).

SumoSprings bellows are the world’s first and only maintenance-free, leak-proof airbags.  Additionally, they have been designed to fit existing competitive airbag bracket systems as replacements for ruptured or leaking airbags.

The SumoSprings bellows are manufactured from patented microcellular polyurethane foam. The combination of raw materials and engineering design produces a smooth ride; provides additional load support; is LEAK PROOF and completely MAINTENANCE FREE.

The SumoSprings bellow top plate has a 4-hole drilling pattern which aligns perfectly with the top bracket of all the Firestone™ and Airlift™ airbag systems cross referenced below. The SumoSprings bottom plate has a centered, single hole. Where this does not correspond with the existing lower bracket system a single 7/16” diameter hole will need to be drilled to complete the installation. (See notes)  Bolts are supplied with the SumoSprings bellows for attachment to the existing bracket system.

Firestone™ / SumoSprings / Airlift™ cross reference sheet.

The SumoSprings will replace all the Firestone (Ride-Rite) and Airlift air spring item numbers listed below with little or no adjustment required. (See notes) Kit numbers are listed to more easily cross reference the appropriate air spring number.
