This 3Racing spare is intended as a direct replacement pulley for the XRAY NT1 brake assembly, offered as a 19T option for scale electric RC use. It is described as an RC-scale accessory for maintenance and parts replacement rather than an upgrade with unspecified performance claims.
Fit and role: the pulley is designed to interface with the NT1 brake components and serve as a service part when the original pulley shows wear. In tuning and setup contexts, replacing a worn pulley helps restore consistent brake engagement and repeatability during practice or events.
Installation notes: verify alignment with the brake shaft and any retaining hardware during fitment, check for free rotation after installation, and confirm the brake linkage operates without binding. Keep routine checks part of regular model maintenance.
