Shocks

I have Bilstein 5100’s on my 1999 F-350. It has a 2” leveling spring in the front so I was able to use them on all four corners. I have about 5000 miles on them over about a year and like them so far. They’re on the stiff side unloaded, but damp well when loaded down. We’ll see how they hold up long term but so far I’m pleased.

Just speculating, but I'd guess it's longer than the 4600, which means you'll bottom out the shock more easily. That may not be readily apparent, but could be uncomfortable on bumps and damage the shock.
They are approximately .75" longer. It won't bottom out, but supposedly there's a risk of the axle drooping far enough to unseat the coil. Having installed and run them on a stock truck I don't think you could drop the coil without removing the sway bar. Even then I'm skeptical.

They were shorter than my Foxs designed for the Carli 2.5 in lift Springs. I have the numbers for the stock shocks, Bilstein's, and Fox written down but I can't remember where.

Been on my truck for 5 years at about 25k miles a year. Looks like its getting time to replace them but they still ride OK. Not great at this point, but OK

That's exactly what happened to me, causing the shock to fail and suspensionlifts.com stating everyting was "fine" even though those shocks aren't made for the front of a 2022 Chevy 3500HD.
