Set of 4: Each product is sold as a complete set of four pieces, one piece for each wheel.
Sierra and Yukon + Denali builds have their own look — usually clean, blacked-out or chrome, running 22s or 24s. Once you go aftermarket on a GMC, the stock-size center area doesn't fill the bore and the whole setup looks unfinished. These XL floating center caps close that gap.
The GMC logo stays upright as the wheel turns. The floating mechanism counter-rotates so the emblem stays level whether you're rolling slow or on the highway. Set of 4.
American Force, Fuel, and Hostile are common aftermarket wheel brands on GMC trucks, and most run a 74mm or larger center cap bore. Measure your center bore before ordering. Gloss black and chrome are the most requested finishes on GMC builds, but all options are available.
Note on Brushed & Polished Aluminum: Machined metal — not painted plastic. $50 upcharge reflected in the price.

You need one of your current caps, a ruler or tape measure, a sheet of paper and a pencil.
Tap your size to select it.
Pick the size closest to your number. A few millimeters either way is normal. 177.8mm (7") isn't available in Brushed or Polished Aluminum.
Start at the last whole number, then count the little lines past it. Each one adds 1/16 in. Example: 5 and 11 little lines is 5 11/16 in, our 145mm size.

Flip the cap over. Measure the raised inner ring that holds the metal clip, outside edge to outside edge, straight across the middle.
Don't measure the hole inside the ring or the wide outer cap.
Tap your back ring size to select it.
