Durable 57T spur for ARRMA small-scale buggies and trucks

This 57-tooth spur uses a 0.5 module tooth profile and is formed from 40Cr carbon steel to serve as a tough replacement in small-scale electric trucks and buggies. It fits common small-scale pinions and is suitable for restoring correct mesh, adjusting gearing, or swapping out a worn factory unit (in some ARRMA kits it replaces a 59T factory spur).

When fitting, set spur-to-pinion mesh carefully, maintain typical RC backlash, and confirm the gear seats flush on the gearbox shaft. After installation, hand-rotate the drivetrain and re-check mesh with no load before operating the model.

Packing includes

  • Spur Gear 0.5 module 57 tooth - 1pcs

Does this match the 0.5Mod pinions on ARRMA GROM and GRANITE?

Yes. The 0.5Mod tooth geometry is intended to mesh with standard 0.5Mod pinions used on the listed ARRMA small-scale models, though checking mesh before final tightening is recommended.

Will swapping from 59T to 57T affect acceleration?

Changing tooth count alters final drive; a 57T spur will typically increase top end slightly and reduce torque compared with a 59T. Verify fit and test on a controlled run to confirm behaviour.

Any quick tips for a tidy installation?

Confirm the gear is pushed fully onto the shaft, secure any retaining hardware, set backlash to spec, and rotate the drivetrain to check for binding before powering up the model.
