This Wheel Hub Extension mounts to your front or rear wheel hub to give you a quick change option when adjusting the width of your kart. Mounts directly to your current wheel hub. It uses a 3/58 bolt pattern so they will work on most European karts, except the front of a CRG which uses a 3/67 bolt pattern.
