Being on the left side it looks like the the anti-lock brake system (pump motor).Pardon my lack of knowledge on these newer 3500 Rams, but is this electronic controller on the top of the left front shock / coil spring, for sway control?
I'll do some research.
TIA.

No. What he’s asking about in his pic that he posted is the ABS module for the brakes.It's an anti vibration motor. There are several of them on the truck.
The anti vibes are under the cab the ABS pump is on the triver coil bracketHmm. I have something similar on my PW under the truck behind the front wheels that's the anti vibration modules.
Maybe if he posted a picture from the top, we coukd have seen the brake lines running to it
But from that picture, it looks just like the vibration modules on my truck.
I outlined the “electronic controller” that the OP is specifically asking about in the pic below. If this is the same thing that you are also referring to, that is the ABS module. This is not some guess that I’m making.Hmm. I have something similar on my PW under the truck behind the front wheels that's the anti vibration modules.

Same spot since at least 2010.Is that for all 2019+ in terms of location? I have never noticed that before, I had to go look, but there it was on my 2024. Learn something new everyday.
Thanks everybody.I outlined the “electronic controller” that the OP is specifically asking about in the pic below. If this is the same thing that you are also referring to, that is the ABS module. This is not some guess that I’m making.
The active vibration cancellation modules that you are thinking off are mounted on the frame behind the front tires.
