Tamiya GF01/TA Series 5mmx6.2mm XM4 Aluminium King Pin by GPM GF004  [GF004]

Aluminium King Pin for Tamiya GF01/TA Series

This is a set of aftermarket aluminium king pins designed for Tamiya GF01 and related TA/TL platforms. The parts reproduce the 5mmx6.2mm XM4 dimensioning from the product name and are supplied as a set of 4 pcs for hinge or knuckle connections on the front steering assembly of RC models.

In use these king pins serve as the pivot point between steering knuckle and hub carrier, so they are primarily a wear item or upgrade target when replacing stripped or fatigued stock pins. Aluminium construction helps resist bending compared with soft metal alternatives while keeping weight low for RC-scale applications.

Installation is straightforward but requires checking mating surfaces such as bushings and bearings for wear before assembly. Tighten to the existing mounting method and verify free movement through the full steering arc; replace any worn sleeves or retainers concurrently to maintain proper alignment and steering feel.
