Taco Air-Ride (Lowering and Leveling) kit?

I've been searching for days on the internet and about a day in these forums and I just can't find what I'm looking for, but I say to myself, it must exist, I'm just looking in the wrong location.

I am looking for a air-ride kit that will drop a taco 2"-4" while standing still (not moving) so my old ass and my wife can stop climbing in. I'm not as young as I was 15 years ago. And then the taco will self-level raising it but to normal height, either when the thing comes out of Park, or by the push of a button.

The other goal here is to provide a smoother ride experience as a daily driver. We have terrible roads at this naval base.

If someone has a link, or if this kind of kit has a special name I can search on, that would be appreciated.

I do plan to replace my 2009 taco (130200 miles) with a 2024 model once I find the one I like and that will be my retirement truck, and hopefully this air-ride kit, if it exists, I could install.
