I am going to swap mine out to a locker. With my 6" lift the rear axle lower arms are at so much of an angle the the welded rear makes it wollow like a pig in mud taking turns on the street.
I will rework the lower arms making them longer and swap in a locker.
On a 2-3" lift it might be fine. Definatly the cheap way out, mine was free. I like it on my sammy.
