This spur gear kit is an aftermarket upgrade for Axial SCX10 and Wraith scale crawlers, pairing a #45 steel 85-tooth 48-pitch spur with a lightweight aluminium adapter. It is supplied as a single replacement set for hobbyists tuning drivetrain durability and gearing on scale crawl builds.
Before fitting, confirm your pinion is 48 pitch, check mesh at the gearbox with the transmission fixed in place, and secure the adapter and spur to the hub according to your chassis mounting style. This is an RC part only and not intended for road vehicle applications.
Ideal for replacing worn 48-pitch spurs or for fine-tuning crawl gearing to gain consistent mesh and longer service life.
