Which UCA is this?

2016 Sierra, October 2015 build date. Is this the forged UCA?

It’s the steel control arm.

Steel. To confirm, take a magnet and see if it sticks to it.

I'm wondering if it's the stamped or forged arm. I'm thinking it's the forged.

Plug your VIN in here and have a look, have your RPO codes handy:

Did that, got this:

I do not have an AVV RPO code in the truck or on the build sheet.

 

Forged description:

Nothing really definitive, but I'm thinking they're the forged arms

cast steel, (looks like a cast iron pan), Aluminum is shiny silver pretty easy to distinguish, and stamped steel is shiny black and smooth and looks more boxy.
