Tamiya GF01 Steel King Pin 5mmx6.2mm XM4, 4pcs by GPM GF004SB  [GF004SB]

Steel king pin for GF01 series

This GPM aftermarket king pin is produced for Tamiya GF01-based platforms and supplies a direct-fit steel replacement for worn steering pivots on RC-scale models. The set contains 4pcs sized and marked in the original item title, intended to restore secure pivot points where the stock pins have worn or been damaged.

Use case: these king pins serve at the steering knuckle and suspension pivot junctions on compatible Tamiya chassis, providing a hard-wearing contact when original pins show play. Installation requires checking mating holes and fasteners for wear and ensuring correct seating to avoid unwanted steering lash.

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