Just looking at the Rough Country site and there are two 3.5 inch lift kits. Im guessing you have the one that is not for the Adaptive Ride Control? Looking at the instructions for the one without Adaptive Ride control it has a sway bar drop bracket included, whereas the one intended for the Denali does not come with the drop bracket. I wonder what the reasoning for it not being included with that one is.

Thank you! That’s what I just learned from the Rough country customer service agent. Still trying to figure out why the sway bar is rubbing. Any ideas there?

Still haven't been able to call the manufacturer so no update from them. But this is the kit that was purchased https://www.roughcountry.com/gm-suspension-lift-kit-29600.html?find=2021-gmc-sierra-1500-4wd-752716 and according to the web page it does fit the Denali.

Hey guys, this is my first time posting here and hoping for some insight or guidance. I have a 21 1500 Denali and about a year ago installed the Rough Country 3.5 inch lift. I took the truck in for an oil change today and mentioned that there was some noise coming from the wheel well. They put it up on the lift and checked everything out and told me that the CV Boot was leaking sue to a puncture from the lower strut bolt. They recommended new front CV axels and a conversion kit for the sway bar. Ive looked around for a "conversion kit" but cant seem to find anything. Warranty was voided with the lift and they dont have a manufacturer sway bar conversion kit so they couldn't do the work. Any help with this would be greatly appreciated!
