Replacement 57-tooth spur for ARRMA and similar small-scale models

This 0.5 module 57-tooth spur is manufactured from 40Cr carbon steel and intended as a replacement component for small-scale electric trucks and buggies. The 0.5Mod profile fits typical small-scale pinions and is suitable for restoring correct gear mesh, changing gearing for tuning, or replacing a worn factory item (it can replace a 59T factory spur in some ARRMA kits).

Install by setting correct spur-to-pinion mesh, observing standard RC backlash practice, and ensuring the gear seats flush on the gearbox shaft. After installation, rotate the drivetrain by hand and re-check mesh with no load before use to prevent premature wear.

Packing includes

  • Spur Gear 0.5 module 57 tooth - 1pcs

Will the GPM 57T mesh with existing 0.5Mod pinions on ARRMA models?

Yes, the 0.5Mod tooth profile is compatible with standard 0.5Mod pinions used on the listed ARRMA small-scale vehicles, but always verify mesh and clearances during fitting.

Is the 57T a direct replacement for the factory 59T spur?

It can replace a 59T in setups where a 57T is required; confirm physical fit and mesh before final assembly to avoid interference or excess wear.

How should I confirm smooth drivetrain operation after install?

Check the gear is flush on the shaft, tighten retaining hardware, set appropriate backlash, then rotate the drivetrain by hand checking for free movement before applying power.
