The Bilstein dampers like (used to?) come stock on the SRTs are dang good. I’ve put them on all 3 LXs I’ve owned so far, and they’ve much improved the ride of each one over its stock suspension dampers.
In an effort to save money, I actually tried several different alternatives on my Charger before finally settling back on the Bilsteins. They are the best out of all the ones I’ve tried so far.
Whatever you get you are going to need adjustable ones, The Viking and the Bilsteins that came on your car are the only 2 I know of that are adjustable. The old SRT "Core" or Super Track Pack Bilsteins are not adjustable.
