WOLLAHS 6.7L Cummins Turbo Actuator for Dodge Ram 2500-5500 (2013-2018) with Calibration Kit & Gasket Hardware

WOLLAHS 6.7 Cummins turbo actuator is a direct-fit replacement for Holset HE300VG and HE351VE turbos on 2013–2018 Dodge Ram 2500–5500 trucks, supplied with a turbine calibration module and full gasket/fastener kit.

This actuator assembly restores variable geometry turbo control and responsiveness for 6.7L ISB Cummins engines when the original unit fails or returns actuator error codes. It is manufactured to meet OEM fitment dimensions and is packaged with the hardware and calibration module needed to install and set the turbine position. The kit is intended for owners experiencing reduced boost, lag, or abnormal turbo noise under light throttle and load.

How will this actuator affect my truck's turbo behavior?

Replacing a worn or faulty actuator stabilizes vane control and improves boost control consistency so throttle response becomes crisper and surges or noise under load are reduced. The included turbine calibration module helps set the correct starting position so the turbo operates within intended parameters.

• Restores precise vane travel for HE300VG / HE351VE turbos
• Reduces intermittent boost drops under light load
• Calibrate module allows accurate initial positioning
• Comes with gaskets and mounting hardware for correct sealing
