If you are talking about the shackle (the part that hangs from the frame and attaches to the leaf spring at the bottom) then yes, the shackle at the front is wider apart than the shackle at the rear. The SPRING is the same size all the way down the length, but the BUSHINGS are thicker (fatter?) on the front shackle than on the rear.
Why? Because the frame member widens a bit as it reaches the front. The thicker bushing makes up for it.
Does that answer your question?
