About This Remanufactured Holset HE300VG — Ram 6.7L Cummins (Part # 5456364HX / 5554227HX) Part numbers 5456364HX and 5554227HX are direct interchange numbers identifying this remanufactured Holset HE300VG for 2019-and-later Ram 6.7L Cummins applications. The HX suffix designates the exchange program. The HE300VG is a variable geometry turbocharger — its adjustable nozzle vanes build boost rapidly at low RPM while maintaining airflow efficiency at highway speeds. When vanes stick from carbon buildup or bearing wear allows shaft play, the truck loses power, fuel economy drops, and black or blue smoke becomes visible. This unit is rebuilt at PT Turbo in San Bernardino, California, with all wear components replaced and the cartridge balanced on a precision high-speed machine before final assembly. Unlike the 2013–2018 HE300VG which used a pneumatic actuator, the 2019-and-later unit uses an electronic actuator — included with this listing, pre-programmed to your engine calibration. Included in the Remanufacturing Process Ultrasonic cleaning and full disassembly New journal bearings and upgraded thrust bearing Compressor and turbine piston ring seals O-rings, gaskets, and snap rings Electronic VGT actuator (pre-paired) CHRA balancing and leak-down test Verify Your Fitment The ISB 6.7L platform spans multiple turbocharger part numbers depending on model year, horsepower rating, and emissions calibration. Confirm part number 5456364HX or 5554227HX against your existing unit before ordering. If you are unsure, our team can verify fitment from your VIN or engine serial number. PT Turbo has been a Cummins ISB turbo specialist since the 6.7L platform launched.
