Tamiya GF01/TA Series Steel King Pin 5mmx6.2mm XM4 GF004SB by GPM  [GF004SB]

Replacement steel king pins for GF01 platforms

This aftermarket king pin set fits Tamiya GF01-based platforms and provides a direct-fit steel replacement for worn steering pivots on 1/10 scale RC models. The pack contains 4pcs sized 5mmx6.2mm XM4 as stated in the title, intended to restore secure pivot points when original pins have worn or been damaged.

Use case: these king pins locate at the steering knuckle and suspension pivot junctions on compatible Tamiya chassis, offering a hardened contact where stock pins show play. During installation check mating bores and fasteners for wear and ensure correct seating to avoid unwanted steering lash.

Maintenance notes: inspect the knuckle bore and adjacent bearings before reuse, confirm smooth rotation without binding after fitment, and replace any companion hardware that shows thread or fit deterioration. These parts are intended for model-level repairs and tuning only.
