Replacement spur gear for small-scale ARRMA and compatible small-scale models

This 0.5 module, 57-tooth spur gear is made from 40Cr carbon steel and intended as an RC-scale replacement part for small-scale electric trucks and buggies. It uses a 0.5Mod tooth profile and is suitable where a direct-fit spur gear is required to restore correct gear mesh, adjust gear ratio, or replace a worn factory unit (replaces 59T factory spur in some ARRMA kits).

Install by checking spur-to-pinion mesh, ensuring backlash is within typical RC practice, and confirming the gear seats flush on the gearbox shaft. After installation, verify free rotation of drivetrain and re-check mesh under no-load conditions before running.

Will this spur fit standard 0.5Mod pinions used on ARRMA GROM/GRANITE?

Yes. The gear uses a 0.5 module tooth profile and is intended to mesh with 0.5Mod pinions on the listed ARRMA small-scale models.

Is this a direct replacement for the factory 59T spur?

The 57T unit replaces certain factory 59T parts in setups where a 57T is required; confirm fit and mesh before final assembly.

What basic checks should I perform after installing the spur?

Verify correct gear mesh, ensure the gear is seated securely on the shaft, and check drivetrain spins freely before running.
