RAYS hub rings are precision-machined aluminum adapters used to make aftermarket RAYS wheels hub-centric on a vehicle. Because many aftermarket wheels have a larger center bore than the car’s hub, a gap can form that causes the wheel to sit slightly off-center. Hub rings eliminate this by filling that gap so the wheel aligns perfectly with the hub.

This proper centering reduces steering-wheel vibration at higher speeds, improves ride comfort, and lowers stress on wheel studs or lug nuts. RAYS manufactures their hub rings in a range of inner and outer diameters to match different vehicle hubs and wheel bores. They’re especially popular among performance-oriented drivers running RAYS wheels like Volk Racing or Gram Lights, where precise fitment is important for both safety and handling.
