2011 f250 - death wobble

I have the death wobble just starting on my front end, 150k miles.

Thinking about just changing the front suspension to an aftermarket suspension that would be softer as we do not tow as much with the truck anymore.

The truck is paid for and we love it, so would like to keep it, just make the death wobble go away and soften up the front end for a more enjoyable ride…

Any recommendations?
