Description Viper 5/16″, & 3/8″ Thick Hub Centric Wheel Spacer w/o External Hub – Fits all Dodge VipersCNC 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 5/16″ to 3/8″ which 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. (** Note: When using wheel spacers, you must use Extended Lug Nuts to make up for lost stud threads on spacer less than .420″ thick. Spacers over .420″ REQUIRE longer axle studs to be installed. **)Wheel Spacers without external HubAll of our wheel spacers are hub-centric by registering on the wheel hub not the wheel studs. Lug Nuts should be tightened in a pattern shown below and torque in 3 steps to help insure wheel centering when lug nuts are tight. “Note: Wheel Spacers fill a cosmetic purpose, not a performance modification. Some sanctioning bodies exclude wheel spacers from HPDE track or competition events.”
