Ram Cummins 6.7 5554226 (2019–2024) Holset HE300VG Remanufactured Turbocharger

Precision Remanufacturing for the Modern 6.7L

The 2019–2024 Ram 6.7 Cummins platform relies on the updated Holset HE300VG VGT turbocharger for responsive boost, efficient exhaust management, and smooth towing power. At Turbo Kings, every 5554226 replacement turbo is fully remanufactured to OEM-grade precision using industry-standard machining, new components, and strict tolerance controls. This ensures the correct vane response, exhaust braking performance, and airflow demands required by the later-generation HE300 architecture.

Our rebuild process begins with a complete teardown and industrial cleaning of all core components. The CHRA is equipped exclusively with new bearings, seals, thrust components, and a precision-balanced rotating assembly. VGT components—including the unison mechanism, nozzle ring, vanes, and actuator drive surfaces—are restored to OEM specifications to guarantee smooth movement under heat and soot load. Each housing is inspected for cracks, erosion, wastegate seat wear, and deformation before being refinished and reassembled.

Seal Integrity, VGT Control & Flow Efficiency

The HE300VG is designed for exact vane modulation at low and high load, so our rebuild process focuses heavily on restoring the turbine section’s airtight sealing and operational smoothness. All sealing interfaces, oil passages, and actuator-mount surfaces are remachined or resurfaced to ensure proper fitment and oil control. The compressor cover and turbine housing undergo resurfacing to maintain precise alignment, reducing drag and preventing vane sticking under heavy-duty use.

Every completed unit is high-speed VSR-balanced and tested to verify boost response, CHRA stability, oil flow, and vane movement. Exhaust braking and commanded vane positioning are validated under simulated load to ensure flawless performance once installed on the truck.

What Makes Turbo Kings Different

Turbo Kings remanufactures turbochargers with engineering-based standards rather than shortcut practices. Our process replaces all wear items, never reuses thrust bearings, and never recycles worn vane mechanisms. Each turbo is rebuilt with consistency and repeatability across units, giving fleet operators and single-truck owners a dependable and predictable replacement.

Our HE300VG reman turbos are built to match the OEM Holset performance curve, ensuring proper throttle response, towing torque, and emissions-system compatibility. Every unit receives a final inspection for visual finish, hardware fitment, torque values, and overall presentation before packaging.

Our Process at a Glance

Why Fleets and Owner-Operators Trust Turbo Kings

Ram 6.7 owners demand reliability, especially when towing, hauling, or running commercial duty cycles. Our remanufactured HE300VG units are built to offer long-term stability, consistent vane operation, and strong low-RPM torque—mirroring the performance of a new Holset unit at a fraction of the cost.

Backed by proven processes and strict testing, Turbo Kings delivers a turbocharger you can install with confidence.
