Look closely and notice that this is a replacement piece, not just a cover.
Billet aluminum interior bezels. Each one individually machined from solid 6061-T6 aluminum. There is NO sheet metal used, no welds, no shortcuts. After machining they get a light media blasting to give them a very light texture and then anodized black. They’re strong and look good (just like the truck they were designed for). You won’t find better made bezels anywhere.
