This socket-head short king pin is designed specifically for the lower bore of the front steering hub carrier on YD-4 family cars. Supplied as a pair, it provides a direct-fit replacement when tuning or repairing the front steering assembly on compatible YD-4 chassis.
Tuning note: replacing worn short king pins can reduce free play at the hub and improve steering precision when used in conjunction with correct chassis hardware. The pin secures the hub to the steering knuckle and preserves geometry when installed to standard specification.
