The SG-4876S by Yokomo is a 48-pitch, 76-tooth spur gear designed for D-MAX series dual-clutch (slipper) assemblies in 1/10-scale R/C cars. It is matched to standard 48P pinions and intended to assist with slipper tuning while maintaining standard ratio characteristics; always verify fit on your specific chassis.
Installation advice: mount the spur to your gearbox hub per the chassis manual, check axial alignment to the motor pinion, and set the mesh using a thin shim or paper test to prevent binding. After initial mesh, confirm slipper preload and test engagement at minimal throttle to validate smooth operation.
Tuning perspective: this spur maintains a familiar tooth count for predictable gearing changes and enables incremental slipper adjustments to manage traction without altering the dual-clutch hardware itself.
