Getting ready to put my new '24 on the road.[has 100 miles]

I've replaced both exhaust manifolds on my 2007 1500 4.7. Both due to broken exhaust manifold bolts, both around 45,000 miles. [one side is leaking again when cold @ 52,000 miles]

Does it make sense to replace the bolts on the 24 while they are nice and new, easy to remove, as a preemptive action to avoid problems in the future? Does ARP make a kit?

As I understand it, on the 5th Gens, the bolts are surviving. It's the manifolds that are cracking due to the brace that's installed on them. You’re better off changing the headers.
