BD Diesel Turbo Actuator HE300VG (1045923) for 2013-2018 Cummins 6.7L

The actuator HE351 used in model years 2013 to 2018 (13-18MY) is an electronic component designed to control the variable geometry turbocharger (VGT) on Cummins-equipped diesel engines, commonly found in Ram trucks. This actuator precisely adjusts the position of the turbocharger’s vanes to optimize airflow, improve engine performance, and reduce turbo lag across a wide range of operating conditions. It plays a critical role in emissions control and fuel efficiency by maintaining optimal boost pressure. Over time, issues such as gear wear or electronic failure can occur, making proper calibration and periodic maintenance important for sustained performance. Replacing or servicing the HE351 actuator often requires reprogramming to ensure compatibility and functionality with the engine control module (ECM).
