About This Remanufactured Holset HE300VG — Cummins ISB 6.7L (Part # 5327358HX)

Part number 5327358HX identifies this remanufactured Holset HE300VG as an exchange unit engineered for specific Cummins ISB 6.7L diesel applications in Ram 2500 and 3500 trucks. The HX suffix designates the exchange program. The HE300VG is a variable geometry turbocharger — its adjustable nozzle vanes allow the engine to build boost pressure rapidly at low RPM while maintaining airflow efficiency at highway speeds. When those 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 remanufactured unit is rebuilt at PT Turbo in San Bernardino, California, with all wear components replaced. The cartridge is balanced on a precision high-speed machine before final assembly.

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
• CHRA balancing and leak-down test
