The Hamilton Cams Flat Tappet Conversion Kit for 2019–2024 Ram 6.7L Cummins trucks replaces the factory hydraulic roller lifters and camshaft with a robust flat tappet valvetrain designed to stop the well-known lifter and cam failures on these engines. This gives late-model Cummins owners the same kind of long-term valvetrain reliability that earlier mechanical engines were known for while remaining emissions compliant in 49 states.
At the heart of the kit is a 178/208 efficiency camshaft matched with DLC-coated steel flat tappets, upgraded heavy-duty pushrods, and adjustable rocker arms featuring DLC-coated trunnions and improved oiling. Together these parts reduce friction, resist galling, and dramatically increase strength, keeping valve timing stable under high cylinder pressure, towing loads, and performance tuning.
This conversion kit is designed to work on otherwise stock trucks with no additional hard parts required, yet it also supports common performance upgrades such as tuning, larger turbos, and fueling improvements. For fleet, tow, and enthusiast customers who want to avoid catastrophic valvetrain failures and expensive engine replacements, the Hamilton 07-CC-24V19+ flat tappet kit is a high-value reliability upgrade for any 2019–2024 6.7L Cummins-powered Ram.
