SumoSprings on a Ford F550

SuperSprings International says its “fit it and forget it” suspension enhancements improve two of the most versatile vocational trucks on the market. Rear SumoSprings, the company’s so-called airless airbags, are now available for the Ford F550 (P/N SSR-104) and Ram 5500 (P/N SSR-303).

Composed of microcellular urethane, they’re claimed to increase load-carrying capacity, provide a smooth load engagement, reduce side-to-side body roll, and improve ride. They’re completely maintenance-free and do not expand outward when compressed.

Since there is no air bladder, SumoSprings will never burst or sag due to leaks, the company says, nor will owners ever have to add air or maintain compressor lines. Testing has shown that the they’ll perform in temperatures ranging from minus-32 C to 93 C.

They’re available in front and rear versions for some trucks and RVs, but the new applications are only for the rear suspensions of 2005-2013 Ford F550 and 2007-2013 Ram 5500 trucks. They use the existing factory holes drilled for the OE bump stops with no additional drilling or fabrication required. Typical installation is said to take an hour or less using standard tools.

Each SumoSpring can be compressed by 80% of its original height with full memory rebound. SuperSprings International offers fleets a 30-day evaluation program.
