25mm Super Drift Spring for R/C (Medium-Soft, Yellow) - Yokomo YOKD119Y  [YOKD119Y]

25mm Drift Spring: Key Facts

This spring is designed for RC drift and general suspension tuning on model cars where a more compliant initial spring rate is required. The yellow marking indicates a medium-soft stiffness, and the 25mm free length fits many compact shock assemblies.

Installation is straightforward using typical spring retainers: compress evenly, seat on the lower collar, then secure the upper retainer so the coil sits true. Confirm the spring runs parallel to the shock shaft to avoid lateral binding through travel.

Tuning tip: introduce changes incrementally and observe one variable at a time. A medium-soft spring will soften initial response versus harder rates, so counterbalance with increased damping or anti-roll adjustments if needed.
