Yokomo R12-14S Steering King Pin for YRX12/R12/GT series  [R12-14S]

Hex-socket king pin for knuckle fitment

This aftermarket king pin is made to fit Yokomo YRX12/R12/GT family knuckles as a direct swap for the factory pivot pin. The button head features a hex socket compatible with a 1.5mm hex key to speed up servicing when you change or fine tune the front end.

The R12-14S has an increased overall length versus the original part so the fixing nut can be fully threaded on even when a spacer is placed beneath the knuckle (spacer R12-14C?420 sold separately), helping to preserve clamp after ride-height or caster tweaks.

Use case: this is a cost-effective maintenance and tuning piece meant to improve fastening security at the knuckle during setup changes, not a structural overhaul. Fit on clean mating surfaces and use the correct 1.5mm hex driver, tightening to a firm but not excessive finish to protect threads.
