Tamiya GF01 King Pin 5mmx6.2mmXM4 by GPM GF004S  [GF004S]

Steel king pin for GF01 series

This is an aftermarket steel king pin set for Tamiya GF01-derived platforms, supplied as a pack of 4pcs. The parts are intended as direct replacements where the original-style king pin is used in the steering knuckle or suspension link joints on RC-scale models.

Use these king pins when replacing worn pins or when a stiffer steel option is preferred for routine maintenance. Installation typically involves removing the knuckle or link, pressing out the old pin, and inserting the replacement; verify thread engagement and secure with the correct M4 fastener as on the original assembly. These pins serve a simple mechanical role and can affect steering feel and long-term wear characteristics when swapped during tuning or repair.
