I went with the arc 3.5 on my high country. So far it’s great not to high for the wife and not to low. I did get the upper control arms also and going into 4x4 is seamless.
Currently on 275/60r20 and my snow tires come summer I have the GM 22 inch wheels and tires can’t wait to see them on the truck. The kit says you can do 295/55r20
