Hamilton 1.45" Tappets for 5.9L/6.7L Cummins (07-t-001)

At 1.45″, they will not have interference with the fuel pump eccentric on 12v Cummins engines and are much wider than the 1.1″ tappets used in early 12v engines. This means they have more surface area to work with wider lobes, which will promote much better lobe life with today's low zinc oils.

• Broad Compatibility: Suitable for 12V, 24V, and common-rail Cummins platforms from 1989 through 2016.
• No Eccentric Interference: Engineered to clear the 12V fuel pump eccentric for hassle-free installation.
• Wider Lobe Contact: With a larger 1.45″ tappet face, these components reduce wear and extend camshaft life.
• Modern Oil Friendly: Higher surface area mitigates the challenges posed by low-zinc oils, preserving crucial valvetrain integrity.

Whether you’re pushing for extra power or simply looking to enhance engine longevity, these 1.45″ Tappets offer superior wear resistance and extended camshaft life—making them an essential upgrade for your Dodge Cummins.
