Hub Centric Ring O.D. 87mm I.D. 70.3mm Chevy GMC Buick

One set of 4 hub centric rings with O.D. (outer diameter) of 87.0mm and I.D. (inner diameter) of 70.3mm. These rings are made of high quality poly carbon. To determine proper fitment you need to do a couple of things. First you need to determine the center bore size, i.e. O.D. of the aftermarket wheel. Contact your wheel dealer if needed. Then find out the vehicle hub size, i.e. I.D. When these match our hub ring description, then they are the right size. These hub rings will fit the following cars and trucks

Fitment and specs

• 87mm outer diameter to match the wheel center bore
• 70.3mm inner diameter to locate over the hub
• Covers Chevy, GMC, and Buick fitments listed above
• Steps an 87mm wheel bore down to a 70.3mm hub

Place each ring on the hub before the wheel goes on so it seats flat. They require no adhesive; the mounted wheel holds them securely.

Common questions

Do hub rings improve the ride?
Yes. They seat the wheel exactly on the hub for accurate centering, which gives a smooth, vibration-free ride at speed.

How do I make sure they fit?
Confirm your wheel bore is 87mm and your hub is 70.3mm. The ring bridges that exact difference, so both numbers need to match.
