      Product FAQs

      What is the capacity of Coil SumoSprings?

      Coil SumoSprings can be used on any application equipped with coil springs and has a GVWR under 14k. They have been tested on trucks, passenger vehicles, sedans, specialty utility vehicles and more. From these tests, SSI has determined that Coil SumoSprings consistently increase the capacity of the coil springs by 15% to 30%.

      Are Coil SumoSprings like other coil spring inserts?

      Traditional coil inserts change the structure of the spring itself by creating separate functioning sections. This split increases coil capacity because it generates stiffness. However, this also decreases coil spring articulation and ride comfort. By using Micro-cellular urethane, the Coil SumoSprings act as a spring within the coil spring. Not only is capacity increased by the change in the spring structure, the progressive nature of the Coil SumoSprings also enhance ride comfort.

      Will Coil SumoSprings help my minivan or sedan’s suspension?

      Absolutely. Coil SumoSprings are very popular on mini vans with bike racks, camping accessories and other equipment. Coil SumoSprings will increase coil capacity to help reduce sag and sway. The same is true for sedans, SUV’s and other crossovers. Some people choose to use Coil SumoSprings on these types of applications simply to tighten up the handling of the vehicle.
