King pins set (for two wheels)

A king pin is the pin about which a steered wheel pivots on the axle of a commercial vehicle.

It forms the steering axis, letting the wheel turn left and right on bushings, while carrying the vehicle's weight and steering loads.

King pins are fitted at the front axle steering knuckles. Because they are central to steering, worn king pins and bushings should be inspected and replaced by a qualified technician.
