The Yokomo ZM-414 Kingpin Set is supplied as a four-piece replacement pack for off-road suspension maintenance. This entry highlights fitment considerations and quick checks to ensure correct installation.
Intended as service spares, these kingpins replace worn suspension pivot pins to recover proper steering geometry and wheel articulation. They are meant for scheduled maintenance rather than being used as a performance upgrade.
Fitting is routine for anyone used to hub service: remove wheel and hub carrier, extract the worn pin, fit the replacement ZM-414 kingpin, then verify the hub rotates freely and spacers or shims sit correctly. Confirm thread engagement and any retainer clips before running the model.
Replacing worn kingpins removes variable slop that can hide suspension setup effects. After replacement, re-check toe, camber, and steering free play to keep chassis feedback predictable.
