SuperSprings International Wednesday introduced new “fit-it-and-forget-it” suspension enhancements for for the Ford F550 and Ram 5500.

Composed of microcellular urethane, SumoSprings’ “airless airbags” increase load-carrying capacity, provide a smooth load engagement, reduce side-to-side body roll and improve ride. However, unlike an airbag, they are completely maintenance-free and do not expand outward when compressed.

The company says SumoSprings have been tested in the harshest environments and will perform in temperatures ranging from minus 25 F to 200 F.

“SumoSprings are truly a ‘fit-it-and-forget-it’ solution for fleets of all sizes,” said Mike Visser, president of SuperSprings International. “They install easily and can be left untouched for the life of the vehicle. We’ve tested SumoSprings across a variety of industry platforms and found that the trucks tend to wear out before their SumoSprings do.”

The new applications are mounted to the rear suspensions of the 2005-2013 Ford F550 and 2007-2013 Ram 5500 using the existing factory holes drilled for the OE bump stops. No additional drilling or fabrication is required. Typical installation takes an hour or less using standard tools.

“Since the SumoSprings urethane compound doesn’t change, designing the new applications was just a matter of figuring out how to best arrange the brackets,” said Visser. “The F550 and 5500 are utilized in many industries and there’s a SumoSprings benefit for nearly every use.”

The microcellular urethane progressively compresses under load, providing the best possible ride in all conditions. Each SumoSpring can be compressed by 80 percent of its original height with full memory rebound.

SuperSprings International offers fleets a 30-day evaluation program. Fleets interested in trying SumoSprings can test a set for 30 days. If not satisfied during that time, they can return it at no charge.
