Queencar VGT Turbo Actuator for 6.7L Cummins 2013–2018 Dodge Ram 2500–5500 with Calibration Kit

Replacement VGT turbo actuator for 6.7L Cummins engines that restores variable geometry control for compatible 2013–2018 Dodge Ram trucks. This Queencar actuator is a direct-fit aftermarket unit designed for Holset HE300VG and HE351VE variable geometry turbos used on 6.7L Cummins ISB engines. The kit includes the actuator, an installation kit and a calibration module so you can replace the failed OEM part numbers (for example 68481772AA / 68445522AA) and re-calibrate the turbo control without sourcing multiple components separately. Materials and testing focus on longevity and compatibility across the listed Ram models.

How does this actuator affect turbo performance on a Ram 6.7L?

The actuator controls vane position inside the VGT turbocharger, which changes boost response across engine speeds. A functioning actuator helps maintain expected throttle response and reduces turbo-related fault codes by restoring proper vane movement and feedback to the engine controller.

• Direct-fit replacement for Holset HE300VG / HE351VE turbos
• Works with factory VGT systems on 2013–2018 Dodge Ram 2500–5500
• Includes calibration box for relearning actuator position
• Aluminum housing resists corrosion and dissipates heat

What installation and calibration steps should I expect?

The package includes hardware, a wiring harness adapter and a product-specific calibration box plus a tutorial. Basic mechanical installation replaces the actuator and linkage; electronic calibration uses the provided programmer to learn vane positions—note special considerations for late-model trucks.

• Follow the included tutorial for mechanical and electrical steps
• 2018+ vehicles may require a security bypass OBD2 cable to program successfully
• Allow time to manually free the turbo linkage if carbon is present before installing
• Test for smooth vane movement after calibration to confirm success

Which vehicles and part numbers are compatible with this kit?

This actuator fits 6.7L Cummins ISB engines equipped with variable geometry turbos in Dodge Ram 2500, 3500, 4500, and 5500 trucks from model years 2013 through 2018. It replaces several OEM references and adapts to certain earlier turbos via the included wiring harness adapter.

• Designed for Ram 2500/3500/4500/5500 (2013–2018) with VGT turbos
• Fits HE300VG and HE351VE Holset turbochargers
• Replaces OE numbers such as 68481772AA, 68445522AA, 5494878RX and others
• Adapter harness enables compatibility with some 2007.5–2012 turbo housings

What should I inspect before installing the new actuator?

Before fitting the replacement, manually move the turbo’s linkage rod to ensure it isn’t seized by carbon deposits. A stuck linkage will overload and quickly damage a new actuator, so cleaning or freeing the vane mechanism first is essential for durability.

• Check turbine blade condition and vane free-play manually
• Clean carbon deposits if the linkage is stiff or immobile
• Verify electrical connector fit and harness integrity
• Confirm part numbers and turbo model before purchase

Who is this for This Queencar VGT actuator kit is aimed at owners and technicians working on 6.7L Cummins-powered Dodge Ram trucks (2013–2018) who need a robust direct-replacement for failed VGT actuators. It suits DIY installers comfortable with turbo hardware swaps and calibration steps, as well as shops that want a tested aftermarket option with spare parts and a one-year warranty. If your truck displays VGT-related codes, poor boost response or a seized linkage, this kit provides the parts and calibration tools to restore proper turbo function—just ensure you have the correct programming interface for 2018+ vehicles before beginning.

FAQ

Q: Will this actuator fit my 2017 Dodge Ram 3500 with a 6.7L Cummins?

A: Yes. This Queencar actuator fits 2013–2018 Dodge Ram 3500 trucks with the 6.7L Cummins VGT HE300VG or HE351VE turbochargers.

Q: Do I need any special tools to program the actuator?

A: You need the included calibration box; 2018 and later models may require a security bypass OBD2 cable to complete programming.
