Purple 13mm Front Shock Springs are designed to upgrade the front dampers on select RC10 kits, providing a tuned front spring rate for improved stability and handling. A pair helps control bounce and enhance cornering performance across a variety of track surfaces.

These front springs are compatible with RC10B6.4, RC10B6.4D, RC10B74.2, and RC10B74.2D front shocks. The purple color signals a specific spring rate, making it easier to tailor suspension to different driving conditions and model setups.
