Built for the heaviest Class A motorhomes, the SumoSprings Front & Rear Kit for Ford F53 24K–26K chassis delivers maximum load support, improved stability, and enhanced ride control. Designed specifically for Ford F53 4×2 platforms, this complete suspension upgrade helps reduce sway, body roll, and front-end dive—providing a safer, more confident driving experience.
SumoSprings are a patented suspension enhancement engineered from proprietary closed micro-cellular urethane. Their progressive spring rate engages smoothly as weight is applied, offering superior damping and consistent performance under heavy loads. Unlike air suspension systems, SumoSprings are maintenance-free, never leak, and require no compressors or airlines.
Each SumoSpring is handcrafted, with natural variations that reflect the premium craftsmanship behind every unit. This combo kit includes a precisely matched front kit (SSF-173-40-2) and rear kit (SSR-183-54-1) to ensure balanced suspension performance. Ideal for motorhomes from Coachmen, Holiday Rambler, Jayco, Tiffin, and Winnebago.
