The steel 68T spur listed as GPM YT068TS is engineered as a direct replacement for Axial Racing Yeti gearboxes. With a 32 pitch tooth profile and CNC-quality finishing, it is intended to replace weaker plastic spurs where increased tooth strength and reliable mesh are needed for performance or longevity.
This spur functions as the primary gearbox gear, meshing with the motor pinion to allow ratio changes or drivetrain refurbishment. Installation follows standard procedures: remove the gearbox cover, document shim spacing and mesh, slide the spur onto its shaft or hub, then verify mesh and bearing alignment before final assembly.
Compared with plastic, steel produces a firmer contact and requires careful pinion alignment and shim selection to avoid premature wear. This item is specified for RC use on Axial Racing Yeti platforms only and is not intended for use on full-scale vehicles.
Recommended when precision, durability and consistent gear engagement are required for Axial Yeti drivetrain upgrades and maintenance.
