Progressive spring technology for improved load support and ride comfort.
Super Springs SumoSprings are engineered to enhance vehicle suspension without compromising the factory ride quality. These progressive springs feature a soft initial engagement that increases resistance as weight is added, providing optimal support and control. Manufactured from proprietary micro-cellular polyurethane, they effectively reduce rear-end sag, minimize vibration, stabilize sway, and soften harsh rebounds, ensuring a smoother driving experience.
With a height of 5 inches and a diameter of 4 inches, each spring has a load capacity of 2800 pounds at 50 percent compression. This design allows for significant compression, up to 80 percent of the original height, while maintaining full memory rebound. The one-piece unit is easy to install and can serve as a replacement or upgrade to factory bump stops, offering superior damping properties and a progressive spring rate.
SumoSprings are maintenance-free and built to last, with no risk of leaking or rupturing. They come with all necessary hardware for installation, making them a practical choice for enhancing load-carrying ability and improving overall driver control and ride comfort. It is important to adhere to the manufacturer's GVWR guidelines when using these products.
