SumoSprings Rear Suspension

The SuperSprings SSR-623-40 SumoSprings are a patented suspension product designed as an upgrade to factory bump stops. These one-piece units attach on one side and are engineered to enhance load carrying ability, stabilize sway, and improve overall driver control and ride comfort. They are maintenance-free, do not leak air, and do not require airlines or compressors. Each SumoSpring is handmade from proprietary closed micro-cellular urethane, providing a smooth and progressive spring rate with superior damping properties. Key technical specifications include a 1400 lb capacity at 50% compression, allowing them to compress up to 80% of their original height with full memory rebound. They are sold as a pair for both left and right sides. The material is a patented micro-cellular urethane. Installation is straightforward as they are designed to replace or upgrade existing factory bump stops. No specialized tools or modifications are typically required, making them a relatively simple DIY upgrade. They are a one-piece unit, simplifying the installation process. While they offer significant benefits for a range of Toyota and Lexus SUVs, it is crucial never to load any vehicle beyond the manufacturer's Gross Vehicle Weight Rating (GVWR). Compatibility is verified for specific models and year ranges, providing targeted improvements for these vehicles.
