Viper .420 Thick Hub Centric Wheel Spacer with External Hub for wheel registration – Fits all Dodge Vipers CNC machined from aircraft 6061-T6 Aluminum, available in .420″ 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. These wheel spacers have an external hub for registering the wheel on and 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. Sold as singles, picture shows internal hub registration and external wheel registration
