Yokomo SG-4872S Precision Spur Gear 48P 72T for Slipper  [SG-4872S]

Precision 48P 72T Spur for Slipper

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

Design focus is on predictable meshing and repeatable engagement for tuning tyre bite and slipper slip. When fitting this spur, verify gear mesh with the motor pinion, confirm slipper preload settings, and use proper thread locking for mounting hardware where applicable. The part is intended for model-level drivetrain tuning and routine maintenance, not full vehicle systems.

Installation notes: remove the slipper assembly cover, match the spur spline to the shaft, set initial mesh with a thin feeler or paper method, and reassemble checking for smooth rotation and consistent slipper action under power.
