This single 55T spur gear is an RC-scale replacement sized for Axial SMT10 and SCX10 II style builds. The component is formed from steel #45 to deliver greater tooth stiffness and wear resistance versus standard plastic gears, making it a practical option for heavy-duty scale drivetrain layouts.
Intended solely for radio-controlled models, this spur transfers motor torque through the gearbox and requires careful setup of pinion engagement and backlash. Align the gear and pinion precisely and confirm bearing clearance; incorrect mesh or over-tightened fasteners can cause premature wear or gear deformation.
The sale covers one 55T steel spur gear, sold as a single pcs unit. Refer to the compatibility list below for the specific fitment code sourced from the original documentation.
Choose this steel #45 55T spur when you need superior abrasion resistance in scale drivetrains, and double-check the compatibility code before fitting.
