Garrett GXR47-76 123mm Ball Bearing Turbocharger – 7+7 Compressor Wheel Technology for Maximum Power & Response

Engineered for racers and high-horsepower enthusiasts, the Garrett G-XRace GXR47-76 123mm Turbocharger delivers elite-level airflow, rapid spool characteristics, and an exceptionally broad powerband. Built around Garrett’s advanced ball bearing center section and featuring an aggressive 7+7 compressor wheel design, the GXR series is designed to maximize both transient response and top-end power for serious motorsport applications.

Whether you're building a drag car, roll racing setup, or high-performance street machine, the GXR47-76 provides the perfect balance between fast response and massive airflow capability. The dual ball bearing architecture significantly reduces friction compared to traditional journal bearing turbos, resulting in improved spool time, enhanced throttle response, and increased durability under extreme boost conditions.

The standout 7+7 compressor wheel configuration improves aerodynamic efficiency while widening the usable RPM range. This translates into a much broader power band, allowing the turbo to pull harder across more of the rev range instead of delivering power in a narrow peak window. Drivers benefit from stronger mid-range acceleration, improved drivability, and sustained top-end performance.
