This aftermarket king pin kit is intended for Tamiya GF01-based cars and offers a steel replacement to restore worn steering pivot points on 1/10 scale RC vehicles. The package contains 4pcs at the sized 5mmx6.2mm XM4 as shown in the product title, to re-establish secure pivot connection where stock pins have failed.
Use guidance: install these pins at steering knuckles and suspension pivot junctions on compatible Tamiya platforms to regain firm steering feel. Before fitting, assess mating bores and fasteners for wear and ensure pins are fully seated to avoid steering lash.
Service tips: inspect knuckle bores and related bearings, check for smooth rotation without binding after installation, and replace any worn companion hardware. These components are supplied for model-level repair and performance tuning.
