Turbocharger HE351CW for Dodge Ram 2500 3500 (2004-2007) 5.9L Cummins

Direct-Replacement HE351CW Turbocharger for 2004-2007 Dodge Ram 2500, Ram 3500 (DR/DH)

What it Does: The HE351CW Turbocharger replaces the worn factory turbo on the 2004-2007 Ram 2500, Ram 3500 to restore boost pressure, eliminate exhaust smoke, and recover critical towing performance.

The Stock Dodge Ram 2500, Ram 3500 Turbocharger Failure Modes

The factory Holset HE351CW on the 5.9L 24V Cummins ISB operates under severe thermal and mechanical loads, particularly when towing heavy payloads or running continuous highway grades. Over extended cycles, journal bearing wear leads to excessive radial and axial shaft play, causing the compressor or turbine wheels to contact their respective housings. High exhaust gas temperatures (EGTs) accelerate carbon coking within the center housing rotating assembly (CHRA), restricting oil flow through the journal bearings and deteriorating oil seals. Consequently, owners experience severe boost lag, persistent blue or black exhaust smoke, oil pooling inside the intercooler boots, electronic wastegate solenoid faults, and dangerous power loss under load.

The Engineering Solution

This replacement turbocharger is engineered to meet original equipment specifications, restoring the high-flow dynamics of the 5.9L Cummins platform. It features a precision-balanced CHRA to eliminate high-RPM vibration and premature bearing fatigue. The heat-resistant nodular cast-iron turbine housing handles sustained thermal stress without micro-fracturing, while the high-nickel turbine wheel withstands severe exhaust velocities. Designed with the integrated electronic wastegate command port, factory-spec oil feed and drain flanges, and a cast compressor housing outlet, it installs directly onto the OEM exhaust manifold without modifications, returning engine volumetric efficiency and towing power to factory spec.

Frequently Asked Questions & Fitment Warnings

Does this fit the DR/DH Ram 2500, Ram 3500?

Yes, this is a direct fit for the 2004.5-2007 Dodge Ram 2500, Ram 3500 equipped with the 5.9L Cummins ISB 325 hp engine; earlier 2003-2004 models equipped with the HY35W or early SO/HO configurations are not compatible.

Do I need to pre-lube the center housing before the initial engine start?

Yes, you must prime the CHRA oil inlet port with clean engine oil prior to connection and flush the intercooler pipes to prevent dry-start bearing galling and foreign object damage.
