This Kyosho MBW020 suspension shaft is a replacement pivot part for aluminium suspension mounts on Mini-Z style assemblies, with a titanium-coated surface that encourages smoother motion.
Function: the titanium coating cuts contact friction in the mount bore, helping the suspension pivot return more consistently and reducing stiction through compression and rebound cycles.
Compatibility & fit: built for aluminium suspension mounts; verify shaft and bore dimensions against your chassis before fitting, since the part is intended as a Mini-Z style spare component.
Installation & tuning role: install by removing the suspension arm and swapping in the MBW020, then confirm free movement and adjust shock preload or damping if necessary; this upgrade targets improved smoothness and repeatable action rather than modifying spring behaviour.
