Replacement steel king pins supplied as a pack of four, sized 5mmx6.2mm XM4 for use on Tamiya WR-02 based vehicles. These pins are a straightforward service item for restoring steering pivot fit on Wild Willy 2 and compatible models.
These components serve as the pivot axis in the steering knuckle assembly; replacing worn pins reduces slop and brings steering alignment back to spec. Check hole clearance and bearing condition before fitting to ensure correct seating.
Installation guidance: remove the wheel and hub, inspect spindles and bushings, insert the new pins and fasten with appropriate hardware. After refit, check for smooth knuckle rotation and correct bearing preload. This is an RC replacement part only.
