57-tooth Steel#45 spur for SMT10 use

This 57T spur is manufactured for Axial SMT10 applications and carries the part number SMJ057T. Built from Steel#45, it is intended as a direct replacement for spurs matching this tooth count and geometry, and it ships as a single spare with the usual small fittings.

Role in setup: the spur determines the final drive ratio and will influence low-speed torque and top speed. Use this spur when altering gearing for improved crawl or faster runs, or to replace a worn component during servicing. On installation, ensure correct pinion-to-spur engagement and verify free rotation through the drivetrain before motors are fully loaded.

Included components (as supplied):

  • 15X33X1 Fibre - 2pcs
  • 5.4X8.2X11.1X1.5 Black Springs - 2pcs
  • 4MM Stainless Steel Lock Nut - 1pc

Compatible Models

  • SSCX2057T

The GPM SMJ057T is an aftermarket replacement geared to Axial-style drivetrains; check fit and mesh when fitting to ensure expected drivetrain behaviour.

What exactly is supplied with the gear?

You receive one 57T Steel#45 spur plus the small parts shown in the list: two fibre shims 15X33X1, two black springs 5.4X8.2X11.1X1.5, and a 4mm stainless lock nut.

Can I use this on non-SMT10 Axial models?

The gear is designed around SMT10 geometry and lists SSCX2057T as a compatible reference. It may fit other Axial models that share the same tooth count and mounting, but confirm dimensions before installing.

Any tips for installation?

Fit the spur and pinion then adjust mesh to avoid tight spots. Rotate the wheels by hand to check for smoothness, and secure the lock nut once the mesh is set.

How durable is this steel grade?

Steel#45 is a commonly used medium-carbon steel for machined gears, offering reliable wear resistance for scale RC spur gear duties when maintained correctly.
