Enhance load capacity and ride comfort with advanced polyurethane technology.
Super Springs SumoSprings are engineered to provide a significant enhancement to your vehicle's suspension system. These progressive springs feature a soft initial engagement that increases in resistance as weight is added, ensuring optimal support and control without compromising the factory ride when unloaded. Constructed from proprietary micro-cellular polyurethane, they effectively reduce rear-end sag, minimize vibration, stabilize sway, and soften harsh rebounds, contributing to a smoother driving experience.
With a load capacity of 1000 pounds at 50 percent compression, these springs are designed to compress up to 80 percent of their original height while maintaining full memory rebound. This unique design allows for a one-piece unit that can be used as a replacement or upgrade to factory bump stops, offering superior damping properties and a progressive spring rate. The SumoSprings are maintenance-free and will not leak or rupture, ensuring long-lasting performance.
Included with the SumoSprings are essential hardware components such as an adapter plate, spacer, flat washer, and nylock nut, making installation straightforward. It is important to adhere to the manufacturer's guidelines and never exceed the vehicle's gross vehicle weight rating (GVWR) for optimal safety and performance.
