This precision replacement king pin is intended for the lower bore of the front steering hub carrier on YD-4 series cars. The part features a socket-head profile and is supplied as a pair, sized to replace worn or damaged short king pins on compatible YD-4 chassis variants.
Function and fit: the short king pin locates in the lower bore of the steering hub carrier and secures the hub assembly to the steering knuckle, helping to preserve steering geometry and wheel alignment when installed with standard chassis hardware. Use it for regular maintenance or when refreshing wear items to restore steering feel.
