It's an ARE cap. It was on the truck when I bought it. I do like it. I put one on my 2001 Chey when I bought it and it still looked good 15 years later. This one appears to be built better than the on I had on my 2001 Chevy. So I hope this holds up as good. They cost more than say the Century, but they make a really nice cap too. If I would have had to buy one when I got the truck, I probably would had purchased a upgraded version Century cap.
It has a more custom look and costs less than the ARE cap. (See the picture of my 2015 Chevy half ton.)
