Thanks for the replies. I think I have it figured out after finding a couple more threads that addressed the issue from a different perspective.

Wow, that is unfortunate. The GM factory 2" lift that comes on the AT4 doesn't even have new UCA's.

Yeah, that is interesting about the differential drop. I did this same lift on my 2011 Tundra and went 2.5" with a differential drop kit. Evidently the differential drop kits that are available will not work with the elevation models.

I have been reading across the internet for weeks and I still cannot find a concrete answer to this question. I have a 2022 GMC Sierra 1500 Elevation limited (3.0L Duramax). In June I had Bilstein 5100's installed and leveled the front 1.5" (#4 slot). I want to go higher but there is no differential drop for this truck. It appears that 2" (#5 slot) is fine without causing problems but 2.5" seems debatable. I do not plan to change the UCA's. I will be adding a 1" block to the rear. The truck is primarily used on road with weekends on gravel roads, so more of a farm truck than a trail runner. Will 2.5" be okay or should I just stick with 2" to be safe? Thoughts????

The channel was simple uni strut channel. I’m can’t remember the exact size but the pic should give you a pretty good idea. The tie downs came from Amazon. I’ve screen shot the item below.

I bought this GMC Sierra 1500 Elevation a month ago and have been thinking about how to mount a bike rack in the bed every since. I didn’t want to drill the bed so I bought some tie down loops made to fit the existing holes. Cut off the loop and ground the surface flat. Then I used it as a bolt base for the channel mount I had in my previous Tundra. Worked great. See pics!!
