WOLLAHS 5494878RX Turbo Actuator for 6.7 Cummins
The WOLLAHS 5494878RX actuator is designed for Holset HE300VG and HE351VE turbos found on 2013–2018 Ram 2500/3500/4500/5500 diesel trucks. The included turbine calibration module and accompanying instructions support calibration to OEM-like performance. The unit emphasizes high-quality materials, durability, and a drive-by-wire style response improvement after installation. It’s positioned as a cost-effective alternative to dealer parts with emphasis on restoring drivability and responsiveness under light to mid throttle.
Key considerations
Check the vehicle year and model to ensure compatibility with ISB 6.7L diesel and the specific VGT turbo used on your rig. Expect a calibration module to streamline the installation. Some users report better throttle response and fewer boost fluctuations after replacement.
Koomaha HE351VE Turbocharger Replacement
The Koomaha replacement targets 2007–2012 Ram 2500/3500 models with the 6.7L Cummins diesel and VGT turbo setup. It lists compatibility across multiple part numbers (68002982AA, 68005452AA, 68048234AA, and others) to cover common 6.7L configurations. This option is positioned as a full turbocharger replacement rather than just the actuator, suitable for customers seeking a complete swap when the factory unit shows wear or failure.
Key considerations
Confirm the correct model year and the presence of a VGT turbo (HE351VE). Replacement parts above may require professional installation, as turbochargers involve exhaust and oil systems. Verify the exact OEM numbers to avoid incompatibilities.
Queencar 5494878RX Turbo Actuator for 6.7 Cummins
Queencar’s actuator targets the HE300VG HE351VE models used on Ram 2013–2018 diesel trucks. The listing notes an important compatibility caveat for later model years requiring a security bypass OBD2 cable to program the actuator correctly. The package often includes a wiring harness adapter—along with typical installation instructions—to facilitate mounting and calibration. This option emphasizes addressing actuator codes, boost loss, and abnormal exhaust-related noises by restoring proper actuator function.
Key considerations
For 2018 and newer vehicles, ensure you have the bypass cable required for programming. Verify compatibility with the specific Ram model and the 6.7L Cummins engine. Installation quality and software calibration impact final performance.
PartsFlow 5494878RX 68481772AA Calibrate Kit
The PartsFlow calibrate kit is designed for the HE300VG HE351VE actuators used in Ram 2500/3500/4500/5500 diesel trucks from 2013–2018. The kit typically includes the turbo actuator, turbine calibration module, a wiring harness adapter, multiple gaskets, screws, ties, and detailed installation guidance. This option emphasizes a complete refurbishment approach, aiming to restore factory-like boost behavior and reliability at a lower dealer price.
Key considerations
Review included components to ensure you have everything needed for installation. Confirm compatibility with your Ram’s exact year and turbo model. Proper calibration is essential for optimal boost control and throttle response.
6.7 Cummins Turbo Actuator Kit By Ouyanglong
Ouyanglong offers a comprehensive actuator kit tailored for 2013–2018 Ram 2500/3500/4500/5500 with the 6.7L ISB Cummins engine. The listing highlights compatibility with HE300VG and HE351VE VGT turbos and includes multiple part numbers to cover various configurations. The kit is marketed as an all-in-one solution with a calibrate kit that supports improved boost control and throttle responsiveness, potentially restoring smoother power delivery and reducing common VGT issues.
Key considerations
Verify the exact vehicle year and model, and confirm the presence of a VGT turbocharger. Consider whether you need a full actuator replacement or a calibration-focused kit. The breadth of listed part numbers suggests broad compatibility, but precise matching is essential for proper fitment.
Buying Guide: Key Purchase Considerations for VGT Actuators
- Compatibility: Confirm your Ram model year, engine code (ISB 6.7L), and whether the truck uses a Holset HE300VG or HE351VE turbo. Incompatibility can lead to fitment and programming issues.
- Calibration Needs: Some actuators include turbine calibration modules or require a wiring harness adapter. Check whether a standalone calibration kit is included or required for your setup.
- Programming and Bypass Requirements: For newer models, certain actuators may need a security bypass OBD2 cable or specific programming steps. Ensure you have the correct tools before installation.
- Installation Complexity: Consider whether you will replace only the actuator or perform a full turbocharger replacement. Full assemblies may require more labor but can simplify diagnostics.
- Quality and Durability: Look for parts built to OE standards with durable materials to withstand under-hood heat and soot exposure. A calibrated kit that restores boost responsiveness can improve drivability more than a bare actuator.
- Warranty and Support: Check warranty coverage and whether the seller provides installation guidance or a video guide to facilitate proper setup.
When selecting an option, weigh the balance between cost, completeness of the kit, and the specific issues you’re experiencing (loss of boost, actuator codes, or unusual exhaust sounds). For most 2013–2018 Ram 2500/3500/4500/5500 6.7L applications with VGT turbos, a calibrated actuator kit or a full actuator replacement paired with calibration tooling typically yields the most reliable long-term performance.
