It is an important distinction that the Bilsteins most of us are talking about are actually RCD Bilsteins, which are Bilsteins that have been reworked by Race Car Dynamics specifically for these Mopars.
Just remember that those of us that are running or have run RCD Bilsteins have experience running them in this millennium on A-bodies (and also E-bodies in my case). We aren't talking about a different part used on a different car in a completely different application several decades before RCD Bilsteins were even available.
Yes, the RCD Bilsteins are kinda spendy. They're worth every penny, as they do make a NOTICEABLE difference in both performance and ride quality. Again, in my case swapping to the RCD Bilsteins was a dramatic improvement compared to the abysmal KYB shocks they replaced. And most of the sets of RCD Bilsteins I have now are a good decade old themselves, so the notion they won't last as long is just silly and nonfactual.
