That makes sense, I will check the descriptions. Thanks!

Good morning, new to the forum, but not GM. This will be my 3rd. I will be going to pick up a 21 AT4 3.0 Duramax this weekend. I’ve been browsing the forum for a while and have picked up a bunch and appreciate all of the good info on here. I test drove one yesterday and while the ride is better than my 2016, I would like to upgrade the dampers. I have a close friend that works for Bilstein so I will be going that route but was hoping someone on here could help clarify some questions for me. Going from Bilstein’s website, they only show the 5100s and 5160s (rear only) available for the AT4. From what I’ve read, this is because the 5100s actually have a specific part number for the AT4 and are a longer stroke to account for the factory lift. Contrary to Bilstein’s website, 4WP shows a ton of options from Bilstein for the AT4. Is this because the fitment is the same they are just assuming you will set the damper to a higher lift position to make up for the factory lift and still achieve stock ride height or why would Bilstein not show these for the AT4 on their website? If that is correct and I understand it correctly, the 5100s from the Bilstein website have a longer stroke meaning you could set it as 0” lift and still achieve factory ride height whereas the 6112s and other adjustable models would need to be set at the 2” lift position to achieve factory ride height? Lastly, it sounds like the consensus on the 5100s is that they are better than stock. I drive 90% on road between city and highway and my off-roading is limited to hunting season, camping and visiting family farms in the country. I don’t Baja or do any fast off-roading and I rarely tow anything but do occasionally have loads in the bed. Would the 5100s be fine or is jumping up to the 6112s a noticeable improvement? Thanks in advance!
