This damper spring is an RC spare intended for Kyosho Mini-Z AWD platforms and MR-03 AWD variants. It fits into standard Mini-Z AWD shock assemblies as a direct replacement to restore or adjust suspension characteristics without changing shock internals.
Fitting is straightforward for experienced modders: remove the wheel and shock assembly, bleed off shock pressure to reach the spring, swap it out and reassemble. Use the correct small tools and confirm the spring is seated correctly to avoid binding across the suspension travel.
As a tuning component the spring alters vertical compliance and the car's transient behavior. Modifying spring rate will influence ride height, initial bite and mid-stroke support on AWD Mini-Z chassis, so change one parameter at a time and evaluate handling on a predictable surface.
