I bet the guy installed larger, stiffer sidewalled tires after the lift and that is what made his truck ride "rough".That's what I figured. A buddy of mine used to work at a dealership and now he has opened up a small shop of his own. He is gonna put mine on. This morning he told me he put a body lift on a GM for a guy and said it made it ride rough. Thought I'd ask.
I'm sure it's already been thought of but just to add on, the body lift won't or at least shouldn't change your ride, but it will change how you add things like grill mounted bars or large engine components. Adapters may be required if you have future modding plans.
Edit: Sorry, I realized you were asking for someone else. This INFO may be common for some, and not so common for others so disregard.
