Engineered for heavier Class A motorhomes, the SumoSprings Front & Rear Kit for Ford F53 20K–22K chassis delivers increased load support, improved stability, and a smoother, more controlled ride. Designed specifically for Ford F53 4×2 platforms, this complete suspension upgrade helps reduce body roll and sway while enhancing driver confidence—without the hassle of air systems.
SumoSprings are a patented suspension enhancement made from proprietary closed micro-cellular urethane. Their progressive spring rate engages only when needed, providing superior damping and consistent performance under load. Unlike air bags, SumoSprings are maintenance-free, never leak, and require no compressors or airlines.
Each SumoSpring is handcrafted, resulting in natural variations that highlight the quality and craftsmanship behind every piece. This combo kit includes a perfectly matched front kit (SSF-170-40-2) and rear kit (SSR-180-54-1), ensuring balanced performance for 20K–22K GVWR motorhomes from brands like Holiday Rambler, Jayco, Tiffin, and Winnebago.
