Designed specifically for Ford F53 4×2 motorhome platforms, this complete combo kit delivers improved load support, reduced sway, and enhanced ride comfort—without the complexity of air systems.
SumoSprings are a patented suspension enhancement made from proprietary closed micro-cellular urethane. They provide a smooth, progressive spring rate that engages only when needed, improving stability and control while maintaining ride quality. Unlike air bags, SumoSprings are maintenance-free, never leak, and require no compressors or airlines.
Each kit is handcrafted, making every SumoSpring unique, with natural variations that reflect its premium craftsmanship. This perfectly paired front and rear combo includes front kit SSF-170-40-2 and rear kit SSR-184-40-1, ensuring balanced performance and confidence on the road.
