Cummins 5484230 Rocker Lever Assembly

The Cummins 5484230 is a front intake rocker lever designed for the valve train system of Euro III 15.0-liter ISX, QSX, and X15 series diesel engines. It transfers mechanical motion from the camshaft to the intake valves, controlling valve opening and closing timing for optimal air intake and combustion. The component is manufactured from high-strength forged alloy steel to withstand high-cycle fatigue and thermal stress in heavy-duty applications. It serves as a direct replacement for OEM part numbers 4972818, 4318206, 4298641, 4059412, and 4059351. This part is engineered to meet ISO 9001:2015 quality standards for durability and dimensional accuracy in commercial vehicle and construction machinery engines.
