But it's bolted right to the frame. So weird that it "works"? Lol... Sacrificial anode would be way cooler so we don't have to worry about rust later in the trucks life

Looks like a Post Covid active tuned mass module. All mass, no module, most likely due to the chip shortage?
Helps with road noise.

Is this the infamous active tuned mass module?

As someone said this is the replacement for the Active-Tuned Mass Module due to supply shortage. Not very active anymore. 
So this is the damper they install when you get a Hemi w. e-Torque (starting sometime mid 2022 production). Hemi w/o e-Torque should have the active module.

I've got the non e-Torque and I have the damper, not the active module.
Yeah that’s weird as the applications are for hybrid but not non-hybrid
Chalk up to supply chain issues I guess
