Complete Case-ih vibra-shank less the shovel.  Fits on a 3" by 4" beam.  Should work on 4300, 4800, and 4900. As with all used shanks, I would recommend replacing the bushing and bolt. The mounting bolt is NOT included.  Total price for this from your local case-ih dealer is approx. $450, Save your money here!!  Please do your own research to ensure that this will fit your application.  May be taken apart for shipping.
