I just got a 2026 with the 5.3. Learning about cylinder deactivation. Which one of these do I buy?

I have been hunting down a “Ticking” sound coming from my 2020 1500 Denali for about a month now and i couldn’t figure it so i took it to the dealer and they couldn’t figure it out either. They did say the sound isn’t coming from a bad or damaged suspension component and that it was okay to drive. I’ve replaced leaf spring inserts and added Spring Things rubber spacers thinking the sound originated from the leaf springs but later realized it was coming from the front of the truck. i am posting this to see if anyone has dealt with this kind of thing before. The video is too long to add here so i am adding a link to a youtube video i made.
