Ball Bearing vs. Journal Bearing

Standard TNT4R T4 turbos use a ball bearing center cartridge for quick spool-up and strong street manners. The Journal Bearing variants (TNT480 JB, TNT476 JB, TNT485 JB, TNT488 JB) are built for higher-power applications where the additional durability and airflow capacity of a journal bearing center section is the priority.
