57T Steel spur tailored for SMT10 applications

This 57T spur gear is intended for Axial SMT10 platforms and is listed under model SMJ057T. Made from Steel#45, it is a direct replacement option for vehicles using this tooth count and profile, supplied as one spare gear with the standard small fittings.

Function and tuning: the spur sets the final drivetrain ratio and thus changes the vehicle's torque and speed balance. Fit this gear when adjusting gearing to favour torque or top speed, or when servicing a worn spur. Always verify pinion-to-spur mesh and rotate the drivetrain manually to ensure smooth operation prior to full-power runs.

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 a practical aftermarket spur for Axial-style drivetrains; confirm compatibility and set mesh correctly during installation for best drivetrain behaviour.

What items are included with the spur?

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

Which models are listed as compatible?

The listing references Axial SMT10 applications and notes SSCX2057T as a compatible model. Double-check the tooth count and mounting pattern on your chassis before fitting.

How should I inspect the gear after fitting?

After installation, hand-turn the drivetrain to check for any binding and verify an even contact pattern on the gear teeth. Re-tighten the lock nut and recheck mesh after a short run.

What are the benefits of Steel#45 in this part?

Steel#45 provides a practical mix of hardness and toughness for machined spur gears, giving reliable wear resistance for scale drivetrain duties when maintained properly.
