Hamilton Cams, Dodge/Cummins,6.7L, FLAT TAPPET CONVERSION KIT with 178/208 Camshaft

This kit replaces the problematic factory hydraulic roller lifters and camshaft to a reliable flat tappet. It is 49 state certified. We are confident it would pass CARB testing, but we don’t do business in California. This kit will fit and is emission certified for all Ram 2019-2024 2500 and 3500 diesels not in California.

It comes with
– 178/208 Forged camshaft
– DLC coated steel tappets
– upgraded pushrods
– Adjustable rocker arms with DLC coated trunnion
Hamilton Cams Complete Kit
Strength, durability, and precision—those are the hallmarks of our Hamilton Cams flat tappet conversion kit™. From forged steel camshafts to DLC-coated tappets and robust pushrods, every component is engineered for maximum performance and reliability. Trust in our decades of research, thousands of dyno tests, and millions of real-world miles to deliver a kit that stands the test of time.

Forged Steel Camshafts
Tighter Grain Structure: Our 178-208 steel cams are forged, not cut from bar stock—resulting in a more dense, more uniform grain structure.
Enhanced Longevity: A natural “halo” in grain structure forms on the exterior of the cam during forging, adding a layer of strength for extended service life.
DLC-Coated Tappets

Gas Carburized & Polished: Each tappet undergoes a meticulous hardening process that gives us the hardness to act as a very stable base metal for the DLC coating
Diamond-Like Carbon (DLC) Coating: This ultra-hard surface finish dramatically reduces friction and wear. While DLC is a big leap forward to lower friction and extend component life, it can be damaged by using incorrect oil, incorrect lash, experiencing valve float or with metal contamination. Thin viscosity oils, do not provide the correct shear capabilities that flat tappets need. it is important that you use 15-40 oils in non-winter conditions or 5-40 sub-zero. Oils with low-zinc, phosphorous and molybdenum do not provide the additive package needed for a flat tappet.
