Hamilton Cams 1.45" Cast Tappets 89-18 Dodge 5.9L/6.7L Cummins ARP-250-6302 Each ReadyLIFT Xtreme-Duty Upper ControlWhen upgrading the cam in your Cummins to a Hamilton, its a good idea to upgrade your tappets with this kit from Hamilton. At 1. 45 they will not have interference with the fuel pump eccentric on 12 valve engines and are much wider than the 1. 1 tappets used in early 12 valve engines. This means they have more surface area to work with Hamilton's wider lobes,which will promote much better lobe life with todays low zinc oils.
