GF01 Steel King Pin 5mmx6.2mmXM4 Upgrade - GF004S by GPM  [GF004S]

Aftermarket steel king pins for GF01 platforms

This aftermarket steel king pin set is made for Tamiya GF01-derived platforms and is supplied as a pack of four. The pins are intended as direct replacements for original-style king pins used in steering knuckles and suspension link joints on scale RC models.

Fit these steel pins when replacing worn items or when a firmer steel option is preferred for routine maintenance. Typical installation steps are to remove the knuckle or link, press out the old pin, and insert the replacement; check thread engagement and secure with the correct M4 fastener as used in the original assembly. Changing to steel pins can alter steering feel and long-term wear during tuning or repair, so inspect mating parts and confirm fit before running.
