The kit comprises a 32 pitch 68-tooth steel spur and a matched fibre slipper pad sized for AXIAL YETI XL drivetrains. The steel component delivers superior wear resistance compared with softer alloys, while the fibre pad provides a stable friction interface for accurate slipper preload adjustments. Intended strictly for scale RC applications.
Assembly notes: set consistent pinion-to-spur mesh and confirm nominal backlash before final gearbox torquing; install the fibre pad on the slipper plate using existing fastener locations and validate slipper disengagement under minimal load to avoid preload-induced binding. Inspect teeth runout and pad seating as part of initial break-in and routine checks.
Tuning and durability: installing the steel 68T spur shifts the final drive marginally and increases service life under high torque scenarios; the fibre pad supports predictable slip thresholds that protect the gearbox and driveline during sudden traction events.
For technical builds requiring robust gear life and consistent slipper behaviour, this 68T steel spur and fibre pad offer a reliable upgrade when installed and adjusted to manufacturer-recommended clearances.
