XRAY NT1 Aluminum Pulley 19T by 3Racing XN1-41/RE  [XN1-41/RE]

19T aluminium pulley for XRAY NT1

This is an RC-scale 19T aluminium pulley produced for XRAY NT1 chassis use by 3Racing, intended as a direct replacement part for the NT1 belt-drive system. The component focuses on consistent belt alignment and durable contact with the drive belt while retaining the original mounting interface of the chassis.

Installation is straightforward: remove the original pulley from the NT1 drivetrain, fit the 3Racing pulley onto the same shaft or hub position, and verify belt tracking and tension after fitting. No specialised modification to the chassis should be required when used with XRAY NT1 components; follow the chassis service manual for retaining hardware and torque practices.

The part serves a tuning role rather than altering core design: swapping to a machined aluminium pulley can help maintain consistent alignment during setup, and it integrates into standard NT1 maintenance checks such as belt tension, pulley runout, and bearing condition.
