This is a single-piece steel spur gear produced by GPM for Axial Racing platforms, specified as 48 pitch with 81 teeth and made from steel #45. It is an RC-scale drivetrain replacement intended for models listed under compatibility, and supplied as a 1pc set.
Functionally the part serves as the main spur gear in a 48 pitch gear train, so confirm the pinion on your motor is also 48 pitch before installation. Standard installation replaces the existing spur gear using the vehicle’s original hardware, set screws, or retaining components while ensuring correct gear mesh and alignment.
For tuning, this steel spur gear is used when you want a durable metal option in place of softer materials, useful for sustained crawling or trail running where wear resistance matters. Verify tooth count and pitch match your gearbox and pinion choices when altering gear ratios.
