Ever had a rear hub slide in? The kart doesn't handle very well when that happens, does it?
Well, we have a solution for you. Simply slide one of these plastic spacers into your hub before installing it onto the axle, and then slide the hub all the way in until it stops. That way, the hub physically cannot slide inwards. This set includes spacers in four different widths, giving you a good range of track width adjustability. Available for either 40 or 50mm axles.
Stop sliding hubs once and for all
