Viper 5/16″, & 3/8″ Thick Hub Centric Wheel Spacer – Fits all Dodge Vipers CNC machined from aircraft 6061-T6 Aluminum, available in 5/16, & 3/8″ thick, 6 X 4.50 bolt pattern. All of our wheel spacers are hub centric, as they register on the bearing hub not the wheel studs. We have two versions of our wheel spacers less than .420″ are too thin to support an external hub, and a spacer that has an external hub. As the Viper has a bearing surface that the spacers or wheel ride on, that is 3/8″ long, you can see there is no way to have an external hub the same size as the internal bore needed to fit on the bearing hub on any spacer less than 3/8″. Our wheel spacers with the external hub start at .420″ thick and go up from there to insure there is enough material to support the wheel and not be knocked off due to a thin web between the internal bore and external hub.
