When considering the same amount of lift needed- we'll say 4-5" for 35" tires. A suspension lift raises the frame, engine, transmission, transfer case, gas tank, body where a body lift just raises the body and leaves everything else lower. With that said, how does a body lift increase the center of gravity more than a suspension lift? It should be less, right?
True ... but ... he's talking the difference between adding the body lift on top of the 3" suspension lift already in place, and just doing more trimming the clear the big meat.
