Colt Cams Tappet Set Dodge Cummins 5.9L / 6.7L

These Tappets come from the same manufacturer as our camshaft cores. This guarantees proper compatibility of metals.

What is unique above others about these tappets is the crown (or convex surface) this is the #1 feature to guarantee rotation on the Cummins 5.9.

Over the last few years we have noticed a huge inconsistency of crown; in fact our customers were sending in brand new tappets that had to have crown put on them. Some of these were flat and we even found one dished. Not acceptable!

After studying the width of the lobe we decided the diameter of the 24V 2nd Generation was the perfect size, we also maximized the crown for the best rotation.
