1.45″ steel tappets for high rpm engines with 110# or heavier valve springs. For use with Steel Cams.
These tappets work with all 1989-2016 Dodge Cummins engines. At 1.45 inch
they will not have interference with the Fuel pump eccentric on 12v
engines and are much wider than the 1.1 inch tappets used in early 12v
engines. This means they have more surface area to work with our wider
lobes which will promote much better lobe life with today's low zinc
oils.
These are the largest tappets you can run in a p-pumped engine.
NOTE: MANUFACTURER WILL NOT SHIP TO CALIFORNIA.
