AXIAL SMT10 Steel Ring Gear Upgrade - SMJ1200/G1 by GPM  [SMJ1200/G1]

Replacement ring gear for SMT10 drivetrains

The SMT10 Steel Ring Gear, model SMJ1200/G1, is an RC-scale replacement designed for use in AXIAL SMT10 gearboxes. This single-piece ring gear is intended to replace worn or damaged ring gears and to help restore proper mesh and rotational stability when matched with the correct pinion and spur gears.

Being steel, the gear focuses on improved wear resistance versus softer materials. Typical installation requires opening the SMT10 gearbox, checking gear mesh and alignment with the pinion and spur gear, and securing hardware with appropriate thread locking and torque values where applicable.

Fit this steel ring gear when restoring SMT10 drivetrain engagement and durability, and confirm fitment before final assembly.
