Built for the heaviest Class A motorhomes, the SumoSprings Front & Rear Kit for Ford F53 24Kâ26K chassis delivers maximum load support, improved stability, and enhanced ride control. Designed specifically for Ford F53 4x2 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.
