This 0.8 pitch, 52-tooth Delrin spur gear is supplied as Version 2 and engineered for MTX-4 scale RC drivetrains. It serves as a low-friction replacement where a lightweight, wear-resistant plastic gear can cut drivetrain drag compared with some heavier composite options.
Fit this gear as a direct swap into compatible MTX-4 gearboxes. When installing, set the gear mesh with the motor pinion to prevent tight contact, remove any molding flash, and confirm the gearbox turns freely by hand before subjecting the assembly to full power. This part is intended for scale RC use only and not for full-size vehicles.
As a Version 2 component, expect installation steps similar to original MTX-4 spur replacements, with attention to correct alignment and secure fastening of the gearbox cover or retainer hardware used on that chassis.
