Garrett GTX5009R Gen II Turbo | 80MM Supercore

The genuine Garrett GTX5009R Gen II Supercore is built for serious competition trucks that need more than a typical S400 or S410 turbo, but are not looking to step into GT55 sizing. With an 80mm billet compressor wheel, ball bearing center section, and a highly efficient GT50 turbine, this turbo delivers the airflow, response, and race-focused performance builders want in demanding truck applications.

This is a true race turbo for purpose-built competition setups, and it has become a strong choice for B-Class racing, Onaway events, Kuhnle Semi Stampede trucks, and Quebec-style uphill drag racing builds.

Why Choose the GTX5009R Gen II

Choosing the right turbo for a competition truck is about more than size. The GTX5009R Gen II fills an important gap in the market by giving builders a charger that offers substantial airflow without forcing them into a larger GT55-style setup. For larger trucks and harder-running race combinations, that makes this turbo a very smart match.

Its ball bearing design helps deliver quick response in demanding conditions, while the billet compressor wheel supports the performance and durability expected from a true race-focused turbocharger. For builders who want authentic Garrett quality and a proven performance foundation, this supercore checks all the right boxes.

Ideal Applications

• Competition diesel trucks
• B-Class race builds
• Onaway event trucks
• Kuhnle Semi Stampede setups
• Quebec-style uphill drag racing
• Custom performance truck builds
• Larger applications that have outgrown S400/S410 turbos
• Racers wanting a strong middle ground before moving to GT55 sizing

Performance Positioning

The GTX5009R Gen II is best described as the sweet spot turbo for truck builders who need more charger than a common S400 or S410 can comfortably provide, but do not want the extra size, weight, and setup demands of a GT55. That makes it especially appealing in competitive truck classes where balancing airflow, response, and overall setup matters.

Notes

• This is a genuine Garrett supercore turbo
• Built for competition and race use
• Best suited for custom high-performance applications
• Excellent option for truck builders seeking a proven race turbo in the GT50 range
