MTX-4 Tuning Pulley 18T MTX4-30/GO by 3Racing  [MTX4-30/GO]

Overview for track and road setups

This 18T pulley is intended for MTX-4 chassis drive systems and is suited to on-road drivetrain tuning. It explains the pulley function in the drivetrain and when to swap tooth counts during setup work.

Compatibility and impact: built for MTX-4 fitment, the 18-tooth pulley sets a specific gear ratio when paired with your current pinion and spur gear. Replacing pulleys produces a noticeable change in rotational speed and final drive behaviour.

Fitment guidance and tuning use: access the pulley by removing the related drive components, confirm correct alignment, and secure it to the drive shaft or hub used on MTX-4 setups. Match tooth profiles and seating for reliable operation under load and to fine-tune acceleration versus top speed.
