Circuit Sports Altrac Wheel Spacer Hub Rings are made of high quality CNC machined aluminum. These slip-on type rings are made with tight tolerances and are to be used in conjunction with our Altrac Wheel Spacers. These rings are designed to ensure that the spacer is concentric with the hub by filling in the space between the hub and center bore of the Altrac Wheel Spacers. They also provide an extended hub surface for users who wish to retain the use OEM wheels and remain hubcentric. This improves wheel fitment and wheel balance as well as prevent damage due to off-centered vibration found in off-brand wheel spacers. For users who are only using OEM wheels who have our Altrac Wheel Spacers, we highly recommend these rings.

For aftermarket wheel applications, any hubcentric wheel ring will fit with the OEM hub size to wheel center bore specifications. However, for use with our Altrac Wheel Spacers, we highly recommend Altrac Wheel Spacer Hub Rings AND our CNC machined aluminum Altrac Hubcentric Wheel Rings for the perfect fit and application.

*Please note: Altrac Wheel Spacer Hub Rings are sold in pairs (1 set = 2 rings). For all four wheel spacers, please order two sets.
