Hardened-Steel 48P 72T Spur for Robust Drivetrains

The SG-4872S is a 48-pitch, 72-tooth spur intended for RC use with slipper-equipped D-MAX series dual-clutch drivetrains. It acts as a replacement or upgrade in the slipper assembly to alter final drive ratio and engagement characteristics without changing the pinion size.

Its design prioritizes reliable tooth contact and repeatable engagement to support tuning of traction and slipper slip. During installation, inspect gear mesh with the motor pinion, set slipper preload correctly, and secure mounting hardware with suitable thread locking where applicable. The item is meant for model-level drivetrain tuning and routine service, not whole-vehicle replacement.

Fitting tips: remove the slipper cover, align the spur spline on the shaft, establish initial mesh using a thin feeler or a sheet of paper, then reassemble and confirm smooth rotation and consistent slipper operation under load.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Are the SG-4872S teeth hardened for long life?

Yes, the SG-4872S uses hardened steel teeth designed to resist wear in typical RC drivetrain service, helping preserve mesh integrity over repeated use.

Can this spur handle frequent club-level running?

For model-level tuning and regular maintenance it is suitable. Confirm correct mesh and slipper setup; the part is not intended to replace complete vehicle systems in extreme conditions.

How should I monitor wear on the spur?

Regularly inspect tooth profiles and check for burrs or deformation. If you see increased backlash or noise, service or replace the spur to maintain reliable drivetrain behavior.
