What are Hubcentric Wheel Spacers?

What does hubcentric mean? Hubcentric is an industry term. If a wheel spacer or PCD adapter is hubcentric it is specifically designed and manufactured to locate precisely and centrally on the vehicles hub. It will also replicate the vehicles hub on the front of the spacer that it will locate precisely in the back of the wheel.

The precision employed in the manufacture of hubcentric wheel spacers and PCD adapters ensures the wheel has no run out and spins concentrically to the vehicle hub. This concentric running eliminates wheel wobble often experienced with flat shim type spacers or on older vehicles with no central hub lip.
