Upgrade your 2004.5–2007 5.9L Cummins with the True North Turbos (TNT) HE351CW 63/67 — a rebuilt-and-upgraded fixed-geometry turbocharger built from the ground up to improve airflow, response, and towing performance over a tired or failing factory unit.

We service a high volume of these turbochargers coming off both OEM and other performance brands, and we've used that experience to build a 63/67 that gets the job done without sacrificing response, towing manners, power, or — most importantly — quality.

Currently a 10–15 business day build time. This unit can be run on stock fuel, but tuning is recommended to make the most of its increased airflow potential.

Features & Benefits

• 2618 milled compressor wheel
• Modified HX40-based turbine wheel — modifications relieve stresses from blade harmonics associated with higher pressure ratios
• Lower drive pressure than a tired factory or generic replacement unit
• Lower EGTs under load
• No core charge required
• Shipped raw; coating optional
• Designed to support up to 640 hp with proper supporting modifications

Why Rebuild Instead of Replace?

Factory and generic remanufactured HE351CW turbochargers on the 2004.5–2007 5.9L Cummins are prone to shaft play, worn actuators, and restrictive stock wheel geometry as miles accumulate. Rather than replacing a failing unit with another stock-spec charger, the TNT 63/67 upgrades the compressor and turbine wheels while addressing the harmonic stress points that shorten the life of common replacement units.

The result is a turbocharger that spools, tows, and holds up better than a like-for-like factory replacement, while still being tame enough to run on stock fuel.

Ideal Applications

• Daily driven 5.9L Cummins trucks needing a turbo replacement
• Heavy towing
• Stock fuel to moderate fueling upgrades
• Owners wanting improved airflow and lower EGTs over a stock-spec replacement

Frequently Asked Questions

What compressor wheel does the TNT HE351CW 63/67 use?

A 2618 milled compressor wheel paired with a modified HX40-based turbine wheel designed to relieve blade harmonic stress at higher pressure ratios.

Does this turbo require tuning?

It can be run on stock fuel, but tuning is recommended to make full use of its increased airflow potential.

Is there a core charge?

No. Black Sheep Industries does not require a core charge for this turbocharger.

What is the build time?

This unit is currently built to order with a 10–15 business day build time.

Does it come coated?

It ships raw by default. Coating is available as an optional upgrade.
