Hub Centric Ring O.D. 87mm I.D. 78mm Chevy/GMC 6 Lug

One set of 4 hub centric rings with O.D. (outer diameter) of 87mm and I.D. (inner diameter) of 78mm. 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.): 87mm, matches the wheel center bore
• Inner diameter (I.D.): 78mm, matches the truck hub
• Application: Chevy and GMC 6 lug pickups with the small 78mm hub bore
• One set of 4 rings
• Made of high quality poly carbon

Seat one ring into the hub-facing side of each wheel's center bore; it should press in flush by hand. With the ring in place the wheel slides over the hub already centered, which makes lining up the lug holes noticeably easier with a heavy truck wheel.

Common questions

How do I know my truck has the 78mm hub?
Chevy and GMC pickups came with more than one hub size, which is why this ring is listed for the small 78mm bore. Measure across the raised center of the hub where the wheel slides over it; if it reads 78mm and your wheels have an 87mm bore, this is the right set.

Will these work with my aftermarket wheels?
Yes, as long as the wheels have an 87mm center bore, which is the outer diameter of the ring. If you are not sure of the bore, your wheel dealer can confirm it, or measure the opening on the back of the wheel.
