XRAY NT1 Belt Pulley 19T Machined Aluminium - XN1-41/RE by 3Racing  [XN1-41/RE]

19T machined pulley for NT1 belt drives

This 19T machined aluminium pulley is a direct replacement for the XRAY NT1 belt-drive system, made to preserve the original mounting interface while improving belt seating and alignment. It is intended for standard NT1 drivetrain layouts and matches the stock fitment points.

Fitting is simple: remove the stock pulley from the NT1 drivetrain, install the replacement on the same shaft or hub location, then check belt tracking and tension. No chassis modification is expected; use the NT1 service manual for correct fastener torque and retaining hardware procedures.

Use this pulley as a tuning and maintenance item rather than a design change: aluminium construction helps keep consistent alignment during setup and ties into routine NT1 checks like belt tension, pulley runout, and bearing wear.
