Geez, I sure wish there was a shop in the Maryland, Northern Virginia area that I could have 1000% confidence in to do the suspension and alignment on my 2019 with absolutely no issues, I'd pick up a set of these graphite wheels and the 325 RGs..
Collar installation is pretty reasonable. Can even be done on the truck. Any off-road shop should be able to pull the shocks out, put the shocks on a wall-mount compressor, preload the shock spring to provide clearance to pop the collar on, then drop back down, and re-install. For alignment, just have to find a shop that knows what they're doing and can align a modified vehicle. Hopefully the same shop can knock out both. Wheels/tires are standard mount and balance. No fancy equipment required.
I reached out to the guys at ADD, and they recommend a shop called Adrenaline Off Road in Burtonsville, MD.
