Extended Lower Ball Joint

The Supermiata Extended Lower Ball Joint (ELBJ) serves as a robust, high-performance upgrade for the 1989-2005 Mazda Miata. Designed as a direct, plug-and-play replacement for the factory lower ball joint, these units feature a forged 4140 CroMoly steel body that offers superior strength compared to the cast OEM component. These ball joints are specifically engineered to optimize handling by providing an additional 2 degrees of negative camber. This geometry adjustment allows for greater front-end grip, enabling the suspension to operate away from the bump stops while maintaining desired alignment settings for improved responsiveness and quicker lap times. They are approved by SCCA and NASA for competition use where such modifications are permitted. Each ball joint is heat-treated for durability and meets ISO TS16949 certification standards. The installation is straightforward, making the upgrade accessible to both dedicated DIY enthusiasts and professional technicians. A 5-year warranty is included with the purchase, noting that the rubber boot is excluded from coverage.
