Valvetrain

The valvetrain in the 6.7L Cummins (2019–2024) controls the opening and closing of the engine’s intake and exhaust valves. It includes components like the camshaft, lifters, pushrods, rocker arms, valve springs, and valves. This system ensures precise timing and movement for optimal airflow and combustion. Built for durability under heavy loads, the stock valvetrain handles the high pressures of a diesel engine, while upgraded components offer improved performance, higher RPM capability, and increased reliability in high-power builds.
