HE300VG 3794756 Turbocharger for 6.7L Dodge Ram Cummins

HE300VG

The HE300VG (3794756) is a Holset VGT turbocharger configuration for the Dodge Ram 6.7L Cummins ISB diesel. This is a different configuration from the HE300VG 3787604 — same turbo model but covering different Cummins assembly and interchange numbers for specific CPLs and model year sub-variants. Both serve the 2013+ Dodge Ram 6.7L platform. Match by the exact Holset or Cummins number on your old turbo nameplate before ordering. Built new, dynamically balanced, ships with gaskets. We supply diesel shops and distributors.

HE300VG 3794756: Second Configuration for the Dodge Ram 6.7L

Cummins produced multiple HE300VG configurations for the 6.7L ISB Dodge Ram. The 3787604 and the 3794756 (this page) cover different sub-variants and CPLs. If you are replacing a turbo on a 2013+ Ram, the surest method is to check the Holset or Cummins number stamped on the nameplate of your old turbo.

3787604 vs 3794756 — which one?

The internal configuration differences (compressor housing orientation, specific calibration) mean these two variants should not be freely interchanged. Match by part number.

Common failure modes

  • VGT vane sticking — soot buildup jams the vane ring. Derate codes, poor throttle response.
  • Actuator failure — electronic actuator motor or gears. Test separately before replacing turbo body.
  • Bearing wear — shaft play at 150k-250k miles on trucks that tow regularly.

Installation

  • This listing does not include the electronic actuator. Reuse yours if functional, run ECM calibration.
  • Replace exhaust manifold and oil drain gaskets (included).
  • Flush oil feed line. Prime turbo before startup.
  • Clear DTC codes and verify VGT tracking with scan tool.
