Basically if you want to do a body lift just remove it. Serves no purpose other than maybe keeping the body on in case of an accident? Although I don't think I've ever seen a car body fly off on an accident. Carmakers do weird things sometimes
It's only on the V-6 Gen 1's. It's not on the four cylinder trucks, so I really (also) don't know what the thinking is on that piece. There never was a bushing there as far as I know.
