This spur gear assembly pairs a #45 steel 85-tooth, 48-pitch spur with a machined aluminium adapter to provide tight tolerances and consistent mesh for scale crawling applications on Axial SCX10 and Wraith platforms. It is supplied as a single replacement set for model builders focused on durability and repeatable performance under load.
Technical fit notes: confirm a 48-pitch pinion is in use, secure the transmission to check mesh at the gearbox, and torque the adapter-to-hub fixings per your chassis method to avoid play. Intended for RC drivetrain use only.
Specifically intended as a precision aftermarket option when replacing 48-pitch spurs or refining gear ratios on SCX10-based crawlers to improve load response and tooth longevity.
