Overview
The 1UP Racing X-Gear 13mm Buggy Rear Springs — Soft 10.25T (Gold) — are designed to deliver a game-changing performance upgrade for your 1/10 RC buggy. Crafted in collaboration with the renowned Japanese spring manufacturer X-Gear Co., these precision-wound 13mm buggy springs are engineered in Japan and rigorously tested by 1UP Racing's Factory Drivers across dirt, clay, glued, astro, and carpet surfaces.
Factory Drivers report their cars feel more "in the track" — delivering improved grip, sharper response, better handling over bumps, and smoother, more predictable jump landings. Soft Gold rears are ideal for low-grip outdoor conditions where extra rear traction is needed for acceleration grip.
