This pair of Kyosho Big Bore rear shock springs are constructed from high-tensile steel, finished in a distinct yellow color to signify their hard rating. Engineered for the Kyosho Big Bore shock system, these springs are designed to provide improved damping and chassis support during aggressive driving and high-speed maneuvers. Their increased spring rate offers enhanced stability and reduced body roll, making them ideal for racers seeking finer suspension tuning and improved handling on varied track conditions.
