Enhance load carrying ability and improve ride comfort with SumoSprings.
Super Springs SumoSprings are designed to enhance vehicle suspension by providing additional support and control. Constructed from proprietary micro-cellular polyurethane, these springs offer a progressive spring rate that engages softly at first and becomes firmer as weight is added. This unique design helps to reduce rear-end sag, stabilize sway, and soften harsh rebounds, ensuring a smoother ride without compromising factory performance when unloaded.
With a load capacity of 4000 pounds at 50 percent compression, SumoSprings are engineered to compress up to 80 percent of their original height while maintaining full memory rebound. This maintenance-free solution is a one-piece unit that can be easily attached on one side, serving as a replacement or upgrade to factory bump stops. The durable construction ensures that these springs will not leak or rupture, providing long-lasting performance.
Included with the SumoSprings are necessary hardware components such as an adapter plate, spacer, flat washer, and nylock nut, making installation straightforward. It is important to note that vehicles should never be loaded beyond the manufacturer's gross vehicle weight rating (GVWR) to ensure safety and optimal performance.
