Hub Centric Ring O.D. 83mm I.D. 78.1mm Chevy/GMC 6 Lug
One set of 4 hub centric rings with O.D. (outer diameter) of 83mm and I.D. (inner diameter) of 78.1mm. 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
Size:Fits Chevy pickup hub of small 78mm bore with wheels having 87mm bore
Fitment and specs
- Outer diameter (O.D.): 83mm, matches wheels with an 83mm center bore
- Inner diameter (I.D.): 78.1mm, matches the vehicle hub
- Made for Chevy and GMC 6-lug pickups with the smaller 78.1mm hub bore
- Sold as a set of 4 rings
- High quality poly carbon construction
Press each ring into the center bore on the back side of the wheel until it seats flush. Then hang the wheel on the hub and tighten your lug nuts the way you normally would; the ring holds the wheel centered the whole time. It is a hand press fit, so no adhesive or tools are required.
Common questions
How do I know my truck has the 78.1mm hub?
Measure the raised pilot in the center of the hub. This set fits the small 78.1mm bore used on Chevy and GMC 6-lug pickups; if yours measures differently, you need a ring with a different I.D.
Does my wheel's center bore have to be exactly 83mm?
Yes. The ring's outer diameter needs to match the wheel bore snugly to center the wheel, so confirm the bore size with your wheel dealer before ordering.
