WOLLAHS 6.7L Cummins Turbo Actuator Kit for Dodge Ram 2500–5500 (2013–2018) — Holset HE300VG/HE351VE, Calibration Module

WOLLAHS 5494878RX is a direct-fit replacement turbo actuator and calibration module designed to restore boost control and throttle response for 2013–2018 Dodge Ram trucks with the Holset HE300VG/HE351VE VGT turbo. The WOLLAHS actuator kit replaces failing or worn variable-geometry turbo actuators found on 6.7L Cummins ISB engines and includes a turbine calibration module, mounting hardware, alignment pin and a full gasket set. Built to meet or exceed OEM fit and function, this unit addresses common symptoms such as sudden boost loss, delayed spool, or intermittent exhaust/boost noise caused by actuator or vane positioning faults. The kit is supplied with written installation instructions to simplify calibration after mechanical fitment.

How will this actuator affect drivability on my Ram?

Replacing a worn actuator with the WOLLAHS unit restores accurate vane positioning in the Holset VGT turbo, which results in crisper throttle response and more consistent boost under light to medium loads. The included turbine calibration module helps ensure the new actuator communicates correctly with the engine control system so performance returns to expected levels.

• Reduces boost drop-offs and delayed spool-up under load
• Improves throttle responsiveness during acceleration
• Minimizes intermittent exhaust noise related to vane misposition
• Calibration module simplifies post-install adjustments

Which engines and years is this WOLLAHS actuator compatible with?

This turbo actuator is made for the 6.7L Cummins ISB found in Dodge Ram 2500, 3500, 4500 and 5500 trucks from model years 2013 through 2018, and fits Holset HE300VG and HE351VE variable-geometry turbochargers. It replaces numerous OEM actuator part numbers, making it a wide-coverage aftermarket solution.

• Compatible engines: 6.7L Cummins ISB (2013–2018)
• Turbo models: Holset HE300VG, HE351VE
