SuperSprings International (Carpinteria, California) announced new upgraded rear SumoSprings for Sprinter 2500 van and RV applications. Part number SSR-329-47 supersedes part number SSR-325-47. The ease of installation for the new part number is identical to the previous version. What has been upgraded is 50% more of SumoSprings’ patented micro-cellular urethane material is used for the new SumoSprings. This provides additional support and sway reduction, particularly for heavily loaded RV’s and vans. The added material increases the amount of energy the SumoSprings can absorb and dissipate, increasing ride comfort and driver control.
