This steel king pin kit is a precision-focused aftermarket replacement for Tamiya GF01-derived platforms, supplied as a four piece pack. The components are intended to serve as direct substitutes for original-style king pins used in steering knuckles and suspension link joints on scale RC chassis.
These steel pins are intended for maintenance or tuning situations where a more robust pin is desired. Standard installation involves removing the knuckle or link, pressing out the worn pin and installing the replacement; verify correct thread engagement and secure with the specified M4 fastener from the original assembly. Upgrading to steel pins can influence steering response and long-term wear characteristics, so inspect complementary parts during fitment and routine service.
