Is this standard frame for the HDs?

I just purchased my first HD truck, a 2021 Ram 2500. I saw this bracing/bracket/framing (see pic) under the front of the truck. Granted, I try not to make a habit of peeking under other people’s trucks when I go to the store, but this really jumps out as something new to me. Perhaps I’ve lived in the half ton truck space too long, but what are these and is it part of the standard build on these HD chassis or something added on? Sorry if this is a dumb question, but I really don’t have experience in the HD truck space.

…and yes, I know I need to wash my undercarriage…insert joke here.

Yes, standard. That is the radius arm, used on solid axle trucks. Older Ram trucks have 2, one top and one bottom, called control arms.

It keeps the axle in place and also has adjustment for castor during alignments

Ah, okay thanks. Yeah, the radius arms on my 1500 were WAY smaller, I was under the impression these meatier ones were primarily used for leveling for 4x4 off-roading.
