i was thinking about this [https://www.cruisencomfortusa.com/hot-rod-series-1] as well.
i didn't click on the "purchase now" button, but if i remember when this was introduced a couple of years ago, it wasn't exactly moderately priced.
however, in certain applications, it may be the best option. i have never been around anyone that has installed one of these kits, so i have no idea if they work reasonably well or not.
