This aftermarket steel king pin kit is intended for Tamiya GF01-derived models and ships as a set of four pins. The parts are designed to act as direct replacements where original-style king pins are fitted in steering knuckles and suspension link joints on scale RC cars.
These steel pins are suitable when originals are worn or when a firmer steel option is preferable for regular maintenance. Installation commonly requires removing the knuckle or link, pressing out the old pin and inserting the new one; always confirm correct thread engagement and secure with the matching M4 fastener as used in the original assembly. Replacing pins can affect steering characteristics and wear patterns, so inspect related components after fitment.
