1Upracing is thrilled to introduce the 1up Racing X-Gear 13mm Buggy Springs, crafted in collaboration with the renowned spring manufacturer, X-Gear Co. of Japan. These springs are the result of their commitment to delivering a game-changing performance upgrade for your 1/10 RC buggy. Meticulously designed in Japan and rigorously tested by their Professional 1up Factory Drivers in the United States, these springs offer a unique combination of quality and race-proven performance. What can you expect when running 1up Racing X-Gear 13mm Springs? Their Factory Drivers say their cars feel more "in the track" meaning overall improved grip and response. In addition to the extra grip, you can expect improved handling over bumpy areas, and a car that's more predictable over jumps and smoother on the landings. These gave the Team the confidence to attack the track, setting new personal best runs and track record lap times in the process!
