XRAY NT1 25T Aluminium Drive Pulley XN1-43/RE by 3Racing  [XN1-43/RE]

25T aluminium drive pulley compatible with XRAY NT1

This 25-tooth aluminium pulley is made as a bolt-in aftermarket pulley compatible with the XRAY NT1 chassis. It is intended as a direct replacement or tuning option where a 25T pulley is required for 1/10 electric touring car drivetrains.

Tooth count and material choice affect shift feel and final gearing; aluminium gives consistent tooth profiles and greater wear resistance than softer materials, helping maintain stable mesh over long runs. The design is meant to match the NT1 drivetrain layout without requiring changes to the chassis geometry or to electronics such as ESCs or motors.

Installation notes: fit the pulley in the NT1 drivetrain location using the chassis mounting method already specified for that position. Check tooth count and pinion/spur mesh on assembly to preserve correct engagement and to reduce premature wear.
