@battlewagon did you ever get those pro comp drop brackets on the rear and did it fix the issue? Post some pics!
Yes great timing on your part actually, the day you posted, was the day I dropped it off for round two at the suspension shop.
I already had the wheel spacers on. Helped, but barely, and may have just been a placebo effect.
Just picked the truck up, and it is good to go. My boys there installed the drop brackets, as well as replaced the sway bar end links with new bushings. They did it incrementally; the sway bar end links helped, and they pulled it back in and put the brackets on. 100% fix. Now I can drive at 75 on the highway without fear of losing my life.
Thanks for the info, help, and support during my journey 01Konvict!
My brother has a very rare Red PPV for sale in Raleigh, please spread the word Konvict; VERY nice truck, leather, etc
