Axial SCX10 48 Pitch Steel Spur 89T SSCX089T by GPM  [SSCX089T]

48 Pitch Steel Spur for Scale Crawler Drivetrains

This specialised spur gear is intended for RC Axial platforms and is supplied as a single unit. Made from steel #45 at 48 pitch with 89 teeth, it takes the place of standard plastic or softer metal spurs to strengthen the drivetrain on SCX10 and Wraith chassis. The part emphasises consistent wear and improved longevity for scale crawler use.

Compatibility is restricted to models using 48 pitch spur gears with SCX10 spacing; confirm that your pinion and gearbox use a matching 48 pitch pinion before fitting. Installation requires setting correct gear mesh, confirming pinion alignment, and ensuring bearings and shaft supports are properly seated to avoid premature wear.

When tuning, this spur is designed to handle greater torque at low speeds and to reduce tooth deformation under load, which helps when swapping pinions for alternate crawling ratios or when fitting heavier motors. Regular maintenance such as cleaning, mesh adjustment and inspection of mating teeth will keep the gear performing well.
