The Power Driven Aggressor HE351 62/67 Turbocharger is a modified HE351 unit built for 2003-2007 Dodge 5.9L 24-valve Cummins trucks. It replaces the stock compressor and exhaust wheels with a 62mm billet compressor wheel and a 67mm exhaust wheel, delivering stronger spool, increased power, reduced EGT, and lower drive pressure compared to the OEM turbo. Oil drain and turbo-to-manifold gasket are included.
- Buy this if... your truck is a 2003-2007 Dodge Ram with the 5.9L 24-valve Cummins and you want an upgraded drop-in HE351 with better spool, more power, and cooler EGTs than the stock turbo provides.
- Do not choose this if... your truck is outside the 2003-2007 5.9L 24-valve fitment range, or if you are running a 12-valve Cummins. This turbo is specific to the third-gen 5.9L Common Rail and late second-gen 24-valve platform.
- Verify before ordering: confirm your truck year is between 2003 and 2007 and your engine is the 5.9L 24-valve Cummins - not a 6.7L or a 12-valve application.
Best match if: 2003-2007 Dodge 5.9L 24-valve Cummins and you want stronger spool, more power, and reduced EGT over the stock HE351
Stop and verify if: your truck is a 6.7L, a 12-valve, or outside the 2003-2007 year range
Most important check before ordering: confirm the exact engine - 5.9L 24-valve only
Next step: if year and engine match, this is a complete drop-in upgrade with all necessary gaskets and hardware included
Fitment Coverage
This turbocharger fits the following applications:
- 2003 Dodge Ram 5.9L 24-valve Cummins
- 2004 Dodge Ram 5.9L 24-valve Cummins
- 2004.5 Dodge Ram 5.9L 24-valve Cummins
- 2005 Dodge Ram 5.9L 24-valve Cummins
- 2006 Dodge Ram 5.9L 24-valve Cummins
- 2007 Dodge Ram 5.9L 24-valve Cummins
This turbo does not fit the 6.7L Cummins or 12-valve 5.9L applications. It is built around the HE351 housing used on the 2003-2007 5.9L 24-valve platform specifically.
62mm Billet Compressor and 67mm Exhaust Wheel - What The Upgrade Actually Does
The stock HE351 on the 2003-2007 5.9L Cummins is a capable factory turbo, but it has real limitations in compressor flow and exhaust wheel efficiency. The Aggressor 62/67 addresses both.
The 62mm billet compressor wheel moves more air than the stock wheel and is machined from billet aluminum for tighter tolerances and stronger structural integrity at higher boost levels. The result is quicker spool and increased power output compared to the OEM compressor.
The 67mm exhaust wheel is where EGT and drive pressure improvements come from. A larger, more efficient exhaust wheel moves spent gases out of the cylinder more effectively, which reduces exhaust drive pressure and allows EGTs to drop. Lower drive pressure also reduces pumping losses and helps the engine run cooler under load - which matters for towing and extended high-load operation.
The combination of both wheels inside the existing HE351 housing means this is a true drop-in upgrade. The turbo mounts in the same location, uses the same connections, and does not require custom exhaust fabrication or inlet modifications.
What Comes With This Turbo
- Power Driven Aggressor HE351 62/67 turbocharger
- Oil drain gasket
- Turbo-to-manifold gasket
Both gaskets are included. You will not need to source them separately for a standard installation on the listed applications.
Towing, Street Performance, and Daily Driving - Where This Turbo Fits
The Aggressor HE351 62/67 is well positioned for towing trucks where EGT control matters, street-performance builds looking for increased power with strong low-RPM response, and daily-driven trucks where a meaningful upgrade over the aging stock turbo is the goal. The 62mm compressor spools quickly enough for responsive street driving while flowing enough air to support increased power output. The 67mm exhaust wheel keeps EGTs in check under sustained load, which is the primary concern for trucks that tow regularly or spend time at higher throttle positions.
What To Check Before Installing
A new turbo goes in on whatever supporting conditions the existing system provides. Addressing these before installation protects the replacement:
- Oil feed line condition - a restricted or contaminated oil supply will damage turbo bearings early
- Oil drain line - restriction on the drain side causes oil to pool in the center housing and leads to seal failure
- Intake side - inspect for cracks, loose couplers, or debris that could enter the new compressor wheel
- Exhaust manifold condition - inspect the manifold-to-turbo mating surface before installing the new gasket
Oil contamination, drain restriction, or intake debris introduced at installation are the most common causes of early turbo failure. Fix the system conditions first so the new turbo has a clean start.
Avoid These Common Mistakes
- Ordering for a 6.7L or 12-valve application: This turbo is specific to the 2003-2007 5.9L 24-valve Cummins. It will not fit 6.7L or pre-2003 12-valve engines.
- Installing without checking oil feed and drain: Turbo bearing failure from contaminated or restricted oil is the most preventable cause of early replacement failure. Inspect both lines before installation.
- Assuming the existing gaskets can be reused: Both the oil drain and turbo-to-manifold gaskets are included with this turbo. Use the new ones - reusing old compressed gaskets on a fresh turbo is how small leaks start.
Part Numbers
Before You Order - Confirm These
- Truck is a 2003-2007 Dodge Ram with the 5.9L 24-valve Cummins
- Engine is not a 6.7L or a 12-valve application
- Oil feed, oil drain, and intake condition have been checked
All three confirmed? The Power Driven Aggressor HE351 62/67 is the correct upgrade - a complete drop-in turbo with billet compressor, larger exhaust wheel, and all necessary gaskets included, built specifically for the 2003-2007 5.9L 24-valve Cummins.
Frequently Asked Questions
Does the Aggressor HE351 62/67 fit the 6.7L Cummins?
No. This turbo is built for the 2003-2007 Dodge 5.9L 24-valve Cummins only. It does not fit the 6.7L Cummins or pre-2003 12-valve applications. Confirm your engine is the 5.9L 24-valve before ordering.
What gaskets are included with this turbo?
The Aggressor HE351 62/67 includes an oil drain gasket and a turbo-to-manifold gasket. Both are included in the box - you do not need to source them separately for a standard installation.
Why does the 67mm exhaust wheel reduce EGT?
A larger, more efficient exhaust wheel moves spent gases out of the exhaust manifold more effectively than the stock wheel. This reduces exhaust drive pressure - the backpressure that builds upstream of the turbine. Lower drive pressure means the engine does not have to work as hard to push exhaust out, which allows EGTs to drop and reduces thermal stress on the engine under load.
Is this turbo a true drop-in for the 2003-2007 5.9L Cummins?
Yes. The Aggressor HE351 62/67 is built in the same HE351 housing used on the stock 2003-2007 5.9L 24-valve Cummins. It mounts in the same location, uses the same connections, and does not require custom exhaust fabrication or inlet modifications.
Why is the compressor wheel made from billet aluminum?
Billet compressor wheels are machined from a solid piece of aluminum, which produces tighter dimensional tolerances and greater structural integrity compared to cast wheels. This is important at higher boost levels where a cast wheel is more susceptible to stress fracture. The billet construction also contributes to consistent performance at elevated boost pressures.
Is this turbo a good choice for towing?
Yes. The 67mm exhaust wheel reduces drive pressure and lowers EGTs under sustained load - which is the primary concern for trucks that tow regularly. The 62mm billet compressor also spools quickly enough for responsive throttle at towing speeds. This turbo is well suited for towing builds as well as street and daily-driver applications on the 2003-2007 5.9L 24-valve Cummins.
