Supplied as stainless steel replacements for the front C hubs on AXIAL YETI JR models, the GPM MYT004S king pins are intended to limit lateral play at the knuckle arm and wheel hub interface. The parts focus on precise fit and reliable alignment to reduce slop that can degrade steering accuracy. Compatible with original and modified C hubs, these pins help maintain consistent wheel articulation and a more predictable front-end response under load.
