Genuine Garrett MONSTER HK Turbocharger for Detroit Series 60 14.0L Engines | GT47 Upgrade

Genuine Garrett HK Series Turbo for Detroit Series 60 14.0L

If you're looking for one of the larger factory turbochargers ever offered for the Detroit Series 60 platform, this is it.

The Genuine Garrett HK Turbocharger was originally engineered for Detroit Series 60 14.0L HK engines, but it has also become a popular performance upgrade for earlier Detroit Series 60 applications looking for increased airflow without stepping into a custom aftermarket turbo.

Unlike the more common GT42-equipped Series 60 turbochargers, the HK turbo features a substantially larger 79mm billet compressor wheel paired with a GT47 turbine wheel. Combined with a relatively tight 1.27 A/R wastegated turbine housing, this turbo delivers impressive airflow while maintaining excellent spool characteristics, making it an outstanding choice for performance-minded street trucks, tow rigs, and working diesel applications.

Built by Garrett to OEM standards, this is a brand-new, genuine Garrett turbocharger—not a remanufactured or aftermarket copy.

Why Choose the HK Garrett Turbo?

The HK turbo stands apart from conventional Detroit Series 60 turbochargers thanks to several key engineering upgrades:

• 79mm compressor wheel for increased airflow
• GT47 turbine wheel for improved high-RPM efficiency
• Quick-spooling 1.27 A/R wastegated turbine housing
• Genuine Garrett OEM engineering and manufacturing
• Direct replacement for HK-equipped Detroit Series 60 engines
• Popular upgrade for many non-HK Detroit Series 60 applications

One unique feature is its boreless compressor wheel, meaning the compressor wheel threads directly onto the turbine shaft instead of relying on a traditional center bore and retaining nut. While this design isn't intended as a direct performance enhancement, it is a hallmark of Garrett's premium manufacturing and high-end rotating assembly design.
