strange noises are normal
My 1/2 ton had a set of these longer/redesigned control arms on it. I had keys and blocks on it, and completely cleared 35s. I have no idea where they came from, they were on the truck when i got it and i have never seen another set of them. Even with mine being cranked that high, my alignment cams were not maxed, and the alignment was perfect. One of my buddies bought them from me when i parted out the truck to put on his cranked yukon.
